I'm certainly a fan of contrasting bias binding or piping. If you choose a patterned fabric for your bias binding or piping, the insides of your garment hold a nice little surprise for the wearer!
I've tried various ways to make my own binding. There are hundreds of tutorials covering the continuous method online, but the ones I have seen instruct you to use a square of fabric. As I like to use fat quarters or offcuts of fabric to make binding, I didn't like the scraps I'd end up with after cutting my piece into a square. There isn't much you can do with those!
After experimenting with a rectangular piece of paper and doing some research online, I came across a way of making bias binding from a rectangular piece of fabric. Best of all, depending on how wide your bias strips are, you end up with little to no waste!
