Fold over elastic - 20mm wide with a thin line running along the centre for ease of folding. This elastic is satin on one side and matt on the other and can be used for binding and finishing raw edges of bras, girdles and other lingerie or stretch clothing items (ie: sports wear).
It's essential to use stretchy binding on stretchy fabrics as you need the 'recovery' fuction of stretch materials to work in partnership with eachother.
To use, align the centre line of the fold over with your raw edge, and ensure that the raw edge is sandwiched between the two free edges of fold over elastic. Then simply stitch down. Best results are acheived with the three step zig zag stich which is standard in lingerie sewing.
