When I blogged about my new blouse the other week some of you mentioned that you’ve never encountered knit bias tape. It is quite rare in Sweden too, not every sewing store has it. In fact I can only think of one store in my hometown who has a decent selection and I buy most of mine from the Swedish mail order vendor Bibbis textil whom I can highly recommend if you are a Swedish reader, she has a great selection of notions at a good price and her service and knowledge is fantastic.
Knit bias tape is made of cotton that is either matte or mercerized and can be used for all sort of bindings on knits, I use it sometime for arm holes and necklines.
But my number one usage is for covering collar seams on knits. As I’m sure you have noticed many ready-to wear-knit tops have the serged seam covered with ribbing, at least the more high end t-shirts and tops has.
Like this t-shirt from Boden:
While it’s not exactly the same, I think bias tape is a good substitute for this sort of finish.
