You know, what's left over after making a flying geese block with the rectangle and two triangles, or the strips where you join two pieces on an angle. I've been saving mine and plan to make crumb blocks. Most of mine are from 2 1/2" strips so they're pretty small. Those from fabrics I'm not crazy about, I use as starter pieces when chain piecing.
I'd love to hear what you've done with them.
I have a bag full but when I last trimmed blocks, I decided to toss them into a plastic shoebox. Guess who found them??? The cat who will do anything to lay on a piece of fabric.
