Use for top edges of bras. This is a firm elastic with great holding power, but it does soften up a bit upon washing. All of these 80% nylon/20% spandex elastics are latex-free so they are good for those with latex sensitivities. The white colour also dyes very well.
Please note that with the new firmer elastic, you may have to increase the back band length of your pattern.
