Don't you just love it when you read or see something that you have never thought of, and would probably never think of, but is a deeply simple and practical solution? Introducing the scraps of binding ball!!!
I saw completely cauchy's frankenbinding and a light went on! Up until now I've put my leftover binding in my scrap bin, but I never use it for string piecing or scrap piecing because the fold is ironed in and impossible to get out. And when I do want to do a scrap binding I have to dig through the scraps until I find it, and it's a pain. But now I have my very own ball of scrap binding ... simple things.
