I've been telling everyone in chat I was going to make this quilt. It's called Interlock. I'm sure it has another name, but I don't know what it is. It's from an old Georgia Bonesteel book called Bright Ideas for Lap Quilting.
I made one of these quilts years ago, now I remember why I didn't make it bigger, all the bias cuts! The blocks finish at 28 inches. This will be a California king quilt when I finish. It's for some friends who are Florida Gator fans. Only 11 more blocks to go.
