This cotton bobbinet is the the real deal - 100% genuine as used in the fashion industry for decades and the stuff you find in many a boned vintage dress. It is also known as Swiss Tulle. The word bobbinet comes from the words 'bobbin' and 'net' because this material is made in the same way as lace is made, on wide looms. It has a soft yet firm hand in that it is strong but not stiff and scratchy like other more commercially available (and not as strong) dress nets.
Favoured by fashion houses such as Dior since the days of the New Look back in the 50's, this Bobbinet fabric is what you find in couture dress foundations it is incredibly strong and durable - see the technical details below.
In corsetry you probably need to form the back and front panels from silk or coutil for strength and to hide boning effectively and you can make boning channels from the same material.
It is 100% cotton and is used in two to four layers with metal boning sandwiched in channels sewing into the layers or in combination with cotton or silk boning channels.
