All about corset making and corsetry components

A blog with plenty of information on Corset Making and corset making supplies.

A new "From the Archives" series will be published every Wednesday and Saturday from 25 February 2023, until 26 March 2023, and these posts will contain 'old' information on corset making which will be updated for the revamped Learn Corset Making information portal whereever that may be.

  1. Metal corsetry boning was invented in the 1800's by the Victorians when their preferred corset boning of choice, whalebone, was becoming scarce and expensive.  The Victorians came up with two types of boning - both with ingenious features for very specific applications in corsetry and both of which are still in use today with no modern adaptation or equal.

    First of all there is flat steel boning, sometimes known as 'corset flats' or  'spring steel'.  There is a reason for this.  Flat steel boning isn't made of any old metal - No.  It is made from sprung steel which means that it is naturally very 'bouncy' and it is very very hard to bend.  Try bending sprung steel and it will bounce right back into flatness.  Why is this best for curvy corsetry?  Because the way a corset works is by creating pressure and tension over the body to create the special hourglass shape that the Victorians and Edwardians favoured.  If you didn't have sprung steel as boning, then the metal rods inside the corset would simply bend and buckle and would not hold a thing in place.  Can you imagine how uncomfortable that would be and how awful it would look?  Sprung steel on the other hand, only flexes in a vertical direction and will keep its shape and provide tension in the right places - as your corset pattern dictates - and because of this, you can use flat steel corset boning to help engineer your final outcome.  For example, if you want to control a larger bust, or if you want to enhance a smaller bust, flat steel boning can be used in strategic places at the side of the bust to help acheive the desired effect by holding your assets firmly in place and pushing the flesh in a certain direction, unlike spiral steel boning which is much more flexible and will simply mould over curves.

    I do not ever recommend pre-bending flat corset bones because doing this removes the tension in the steel which negates it's special properties.  If you feel like you want to create very curvy drama or you are boning a corset with a very small waist, then use spiral steel boning instead - it will do the bending for you.

    Flat steel boning is also used in hooped petticoats, steel dress cages and panniers and is also sprung so that it keeps it's nice round shape but it is not so thick as flat steel corset boning.

    The Elliptical cage crinoline was the main support foundation for the later- and post-American Civil War period of 1863-1868. Called a "cage" because of the cage-like appearance created by the hoop wires and vertical support tapes, this type of crinoline offers maximum support capabilities for a perfect shape, combined with flexibility for comfortable wear

     

    Spiral steel boning is very different to flat sprung steel boning.  It is made from 2 springs flattened and then forced together to make one flat looking spring.

    This type of corset boning is also sprung and is ingenious because it flexes in all directions and is therefore particularly good for the more curvy areas of the body, where you need a bit of moulding - over the breast, over the hips, perhaps over a fuller dierriere.  Spiral steel boning is much 'softer' on the body and therefore wearers find it more comfortable.  Where flat boning can be used to control and streamline, spiral boning can be used to enhance and create drama.  Spiral steel is the most versatile type of corset boning, it comes in different widths and different thicknesses for all sorts of boning projects and ofcourse it isn't just used for corsetry, it is used in couture for boning dress foundations properly.

    In summary, boning can be used in many ways and many combinations.  Sometimes it can even be used to even out an asymetry in the body.  No body is the same, and it follows that no handmade custom or bespoke corset will be the same as another in terms of how it is boned, however each individual maker will have his or her preferred way of using the bones and this in turn will contribute to the over all look, feel and style of that maker.

    I therefore encourage everyone to experiment with boning and have put very precise descriptions in my product listings.

  2. At Sew Curvy I only stock quality products in the shop which I myself use and can recommend.    I have a variety of cutting tools in the studio but here are my favourite recommendations for sale:

    When I cut out patterns - any patterns - from corset patterns to dressmaking patterns, to purse patterns and everything in between - I use a 45mm rotary cutter and large cutting mat.  Many people who pass through my studio express terror at the thought of  amputating their fingers while using a rotary cutter but I say it couldn't be more simple and whats more, you get a much more accurate cut with a rotary cutter because you don't have to lift the fabric you're cutting at all, and you can keep the cutting blade sharp at all times with the use of replacement blades or a special sharpener for rotary blades.  The cut you get when using a rotary cutter is sharp, clean and even.  Once you get used to using one, you wont want to go back to traditional dressmaking scissors or tailors shears for anything!  

    In corsetry and dressmaking I find that the best size of blade for rotary cutting, is the standard 45mm.  Rotary cutters do come in all manner of shapes, sizes and formats, with standard, luxury and 'deluxe' versions and you can also get different types of blade too.  The 45mm size is big enough to cover distance quickly but small enough to negotiate tight curves efficiently.  Anything smaller would be tedious and anything bigger would be too clumsy.  The array of accessories for rotary cutters can be quite confusing but generally I find that a regular rotary cutter with retractable blade is the most cost effective and easiest tool to use and I prefer Olfa as a brand.   Handy tip for dull rotary blades:  When they are too dull to cut fabric, you can use them to cut paper, cardboard or interfacing with prescision.  Simply 'condemn' the not so sharp blade by paining a blob of nail polish on it to diferentiate it from your sharp blade.  The blade can be kept safe in the special plastic case which comes with every Olfa replacement blade.

    Scissors are of course useful at other times.  I tend only to use dressmaking shears for cutting lengths of fabric and of course it is absoloutely essential that you keep any dressmaking or fabric crafting scissors only for cutting fabric because cutting other materials such as paper, will dull the blades very quickly (although it is possible to have your scissors sharpened professionally in a hardware store).  If kept properly and treated well, a good pair of scissors will last a lifetime so it really is a false economy to buy cheap ones.  

    Applique scissors are sometimes known as duck bill scissors and are good for grading seams or working with layers of delicate fabrics - they have a lower blade which is wider than the top blade and this lower blade protects fabric underneath the scissors while the super sharp top blade cuts the fabric at hand.   We also have super sharp stork embroidery scissors in two sizes and these are a timeless classic - show me a grandmother who didn't own a pair!  I know I was always fascinated as a child by the little silver pair owned by my Nana and this is why these scissors do have a special place in my heart.  Practically, they are fantastic for precision cutting of small areas and for snipping thread ends very close  to your project. The applique scissors and the stork scissors on site are all made by quality German brand Klasse.  

    Small general  sewing scissors about 10cm (5") long are good for small cutting jobs like snipping notches, seam allowances, going around corners and other general fabric cutting where you need power and presicsion but don't want a large wiedly pair of scissors. I stock Fiskars small sewing scissors for this job as they are a lovely handy size  with very sharp pointy blades.  

    The humble stitch ripper should not be overlooked here.  It is every bit as important to keep a sharp seam ripper in your sewing tool box as it is to keep sharp sewing scissors and cutters to hand.   Dull blades = ripped fabric and shredded seams,  and seam rippers do not stay sharp for long - the more stitches you rip, the quicker the blade will blunt.  With this in mind,  I really don't believe in buying expensive seam rippers with fancy handles because they do need replacing frequently so you wont find anything above 50p at Sew Curvy and I frequently send out a free stich unpicker with big orders as a little token of thanks, because I think it is really really important for perfect sewing.  Infact, seam rippers are such a versatile sewing tool that some people write entire blog posts about their many and varied uses - here is one such blog post which will give you 9 other reasons why you need a seam ripper in your sewing box:  10 reasons to love your seam ripper 

  3. A prospective student asked me today how she could better prepare for one of my classes in the New Year.  She told me that she had enroled in dressmaking classes in order to get used to sewing again. I responded that "As long as you are confident with the sewing machine, and comfortable with using one you will be absolutely fine.  Good corsetry is more about organisation, attention to detail, problem solving and accuracy than having amazing sewing machine skills."  It then occured to me, while writing to her, that the way I got good at corset making, was through making bags!

    How on earth, you may ask, does making bags make you good at corsetry?  WELL ....

    Bags are small items which can be made from scrap materials.    Sewing bags is therefore more 'relaxing' than sewing corsets because one of the biggest worries which can impede progress is immediately removed.  Wasting expensive fabric.  That isn't the main reason though.

    Making bags - good bags - involves sewing with lots of layers of fabrics in order to give the bag enough body to be useful and stand up to every day use.  Nobody wants a floppy bag do they?  So a typical handbag will have a good three or four layers inside it.  You'll have an outer layer of strong heavy fabric - perhaps wool, or if it's a light bag, then perhaps a cotton interfaced with fusible webbing.  Then you'll have a middle layer of a very thick interfacing, often this will be the type you use for curtain tie backs - strong enough to add a good deal of body and then there will be a lining.  If you like a challenge, that lining will contain pockets, zips, buttons and other exciting baggy features.

    In addition to sewing through many thick layers, bag making can be quite intricate once you get into more exiting shapes and sizes.  There are sharp corners to navigate (with all those layers), curves to tame, embellishments to add and perfect symmetry to acheive.  Try adding a smooth line of piping or a frill into a small bag with 4 layers already.  

    There are other features about bag making which will challenge your constrcution and problem solving skills you might want a bag with a flat bottom and feet - how to insert a plastic tray to keep the bottom solid, waterproof and strong in that case?   How best to insert your magnetic snap? How to ensure your purse clip doesn't come undone after 2 uses?  How to make a neat transition between bag software and hardware.  All of these thought processes are usefull, if not essential in corsetry, they are just applied in a different way.

    bags for corset making

    And so it was, after I had discovered corsetry, I took a year off work for health reasons, and instead of making corsets, I made bags.  This wasn't a concious desicision to improve my corset making because at that time, a career in corsetry for me was about as far away as Katmandu, it was just a highly creative time  when I had to make stuff which was quick, satisfying and pretty.  Hence bags.  I got good at making them and I can honestly say, that bag making with all it's intracasices - and a fair few were flung across the room in a temper I can tell you - made me better at sewing, and eventually good at corsetry.

    Here are some good bag making resources:

    The woman who inspired a thousand craft businesses - including mine - Lisa Lam's U-Handblog where you'll find lots of bag making tips and tricks to go with her business U-Handbag where you can find the supplies to make said bags.

    Sew Christine is another lady who has lots of bag making tutorials on her blog, and who also has a little supply shop

    There's my old old blog Marmaladekiss which documented all of this frenzied bag making and then progressed into dressmaking and corsetry.  You have to start right back at the beginning to get the good stuff, and in the last 3 years it's been as good as dormant.  However, the odd faithful reader pops up now and then and says how much they enjoyed reading it in it's hey day.

    For other resources, because I haven't made a bag in years, go to The Sewing Directory the go to resource for everyone who's into sewing.

  4. The corsetry net at Sew Curvy is made from a strong polyester fabric similar to nylon, and  suitable for all types of corsetry.  Unlike softer nets such as silk bobbinet or stretchy nets such as power net, this polyester net is like any other non stretch strong fabric and you can make a corset with the standard four inch reduction without worry that it will tear or buckle.   It is sheer, durable and very very strong and can be used on it's own or with lace and other sheer fabrics for extra drama.

    There are some considerations to bear in mind when working with sheer net.  You must use external fabric bone channels if you don't want the bones to show, and you need to consider the inside finish a bit more because unlike a solid fabric where things can be hidden with lining, with a sheer fabric, everything is on show.  However, with some imagination, spectacular effects can be achieved.

    This net can be ironed with a cool'ish iron, and can be sewn using regular polyester thread or with clear/invisible nylon thread, all of which are stocked at Sew Curvy.

    Available in black or natural - the net is BACK IN STOCK! So hurry and get yours, it does have wings!

  5. At Sew Curvy we have quite a large range of bust forms.  We have them in various sizes, colours and types.

    There are the regular fabric style bust form which are quite 'round' in appearance and are made of a moulded fabric which feels a little bit like a fine felt.  And we have the 'swimwear' version which are more flexible in feel and I think, more realistic in shape.
    photo 


    The regular bust forms can be used in dressmaking, the swimwear bust forms can obviously be used in swimwear and bikinis (or even corseted swimming costumes?)  and both types of bust form can be used in corsetry.  What would you do with them?  You can either use them to make a 'modest' cup under a sheer panel - ie, the panel will still look sheer at the bust but you won't be able to see the 'naughty bits' - or you can insert them into the bust in dresses and corsets for more shape or dimension, or you can use them as a mould for cupped corsets.  The range of uses for these marvellous things is actually quite limitless.  Just think about it.  Use a bust form to drape a cup pattern for your cupped corset.  Once this is done, attach your covered cups to an underbust corset pattern.  Experiment, explore, have fun with them!

    The regular forms come in the cup sizes you may be familiar with but are a bit on the small size, and the swimwear cups come in small, medium or large and look out for a cupped corset masterclass at Sew Curvy HQ, in the Spring with the wonderful Alison Campbell of Crikey Aphrodite!

  6. For good corsetry, you need two part metal eyelets with a wide'ish collar - not too wide so as to look clumpy and bulky, and not so narrow that the fabric soon works its way from under the rim and the eyelet falls out, ruining the corset.  Also the shank of the eyelet must be not too long so the eyelet is loose when set, and not too short so that the eyelet cuts the fabric when set.  It's a fine balance !

    You need two part eyelets because the washer part of the eyelet, sandwiches and encloses the fabric safely and ensures a smooth finish to the inside of the corset.  One part eyelets which do not come with a washer,  are not strong enough for corsetry.  One part eyelets are commonly used for leather work - in belts or as a decorative feature, or in paper craft.  They are made of softer metal and when hammered, the back of the eyelet shaft collapses and can become jagged.  This will not only feel scratchy against the wearer and possibly cause injury or damage to other clothing, but it will certainly decrease the life of the corset substantially by causing wear to the fabric of the corset around the eyelet. 

    My favourite eyelets for corsetry are 5mm wide  however, not all eyelets are created equal!  You need different dies to set different eyelets. Dies are the little tools which help to set the eyelets properly either by pliers or by hammer.   Prym make it easy by providing an all inclusive eyelet kit which includes a set of dies that fit the separate Prym pliers which in turn do a marvellous job of not only punching a small hole for the eyelet, but setting them too, with hardly any effort.  However, these pliers only work with Prym eyelets and the same is true of all other eyelets - they only work with the die's that are made for them.  Annoying, but true.  Therefore, in order to make a good job of setting your eyelets, you do need the correct set of dies.

  7. Sew Curvy corset lacing is specially made for Sew Curvy in a British Factory.  It 100% cotton and woven in a flat tube 7mm wide. This flat tubular weave provides maximum strength and durability.  Sew Curvy lacing is used by the world famous Cirque du Soleil for their trapeze artists' costumes - they like it because it is strong, yet flexible and soft.  

    roll of laces
    Because the lacing is cotton, it can easily be dyed to match the colour of your corset.  There are instructions on how to do this in the Tutorials section of the website.  Try using tea or green tea to dye your laces a 'natural' colour.

    I do not supply finished laces, that is to say, with metal ends in given lengths.  Why?  Because those laces are exactly the same, but cost at least three times as much. However I do supply it either by the metre, or in a whole roll of 100m.  Continuous lacing is economical.
     
    Ends can be finished with a knot - which will be invisible when your corset is laced, or you can whip the ends with embroidery floss or stitch on special cord ends or aglets.

    For corsets, you only need one length of lacing which is tied in the middle via 'bunny ears'.  I would recommend 4m for a short underbust corset, and up to 7m for a long overbust.

  8. I often put a little freebie into my parcels going out to regular customers - only something little as a token of appreciation for their continued support of my business.  I bought a big bag of seam rippers from my wholesaler, to sell on the site, but also to use as a little free gift.  However,  so far, haven't put any of these into a package unless they have been ordered.  Why? I  am frightened people might get the wrong idea about my opinion of their sewing! - a bit like giving someone smellies for Christmas .. 

    The thing is, a sharp seam ripper is an absolutely vital tool for any seamstress or corsetiere.  Believe it or not, seam rippers get blunt very quickly.  The better you are at sewing, the blunter your seam ripper is likely to be.  It's a sad fact but I probably use my seam ripper, more than my sewing machine! 

    Now these seam rippers are the best I can find and the cheapest!  They cost £0.50p.  I don't believe in spending lots of money on a seam ripper because you do have to replace them so often.  Before I bought in bulk, I would buy 4 or 5 of these seam rippers at a time from my local haberdasher.   I still always make sure I have a personal stock of these and mark my current one with a blob of nail varnish - this way, the new sharp ones don't get used until the current one is blunt and in the bin. 

    If you get into the habit of using a sharp seam ripper, you will soon know and appreciate the difference between a sharp one and a blunt one - a sharp seam ripper will unpick your stitches faster and with much less risk to the rest of your sewing.  So! If you haven't replaced your seam ripper for a while, I urge you to assess the situation and replace  your seam rippers frequently for best sewing results. And if you do happen to get one from me that you didn't order, it's a gift but not in a bad way ;)
