I've found that if I'm planning on making one quilt, it's not much more trouble to cut out enough fabric to make two. I got most of the fabric for the butterfly wings from my stash. I've made two of these quilts, now. Love this block! It's from Mrs. Schmenkman's blog. You can find a tutorial there. It's even got a little wiggle room built in, just in case you need to fudge a bit.
