I've done several lasagna quilts with my less then WOF cuts. It was fun just randomly sewing the smaller pieces together and rolling them up until I had enough to make the quilt. I used up a lot of my fat quarters for that project.
I was tired of my fat quarters, had them in my fabric stash and I'd grab it thinking it was enough to do a project and then get annoyed when it was only a fat. I bought them years ago when the LQS was having a big fat quarter bonaza. If I'd been smart I would have put them all in a separate bin, but wasn't thinking.
