What is stretch bias? Not to be confused with FOE (fold over elastic). Stretch bias biding is a narrow strip of stretch fabric cut crosswise. You can find this item pre-made (ready to use) or you can make your own using the same fabric of the main garment.
To finish a garment with ‘stretch bias’ is very easy. It is exactly like sewing a woven bias biding. I already demonstrated a step by step visible bias application which use a double folded bias tape.
For a invisible finish like the wren or the ultimate wrap dress you will need a single fold bias. Victory Patterns has a lovely tutorial encompassing the different woven bias application. Just remember you don’t need to stretch it, ok. Just threat it like a woven bias. Next wrap dress that doesn’t have a facing I will take step-by-step pictures and update this post for a more comprehensive explanation.
Ps: Cutting Class always have interesting takes on a topic, bias binding inclusive.
