ArtLady posted photos of mitered square things she's done, which I think included an afghan. They have lots of possibilities for making really interesting pieces. When I was told they're easy I thought, yeah, right, but they really are. Have fun. I'm thinking of interesting ways to use them. You'll probably come up with lots of ideas, I'd love if you shared them.
Happiness is catching that dropped stitch while it's still fixable..
