It's very unusual for me NOT to piece my backsides.
Whenever I give a quilt to a family member the first thing they do is to flip the quilt over to see what's on the back.
This weekend I'm working on a simple back made from 5" squares ranging in color from brown to white-on-white. It will only take 676 (insert crazed laughter here) I've only got about 100 more squares to cut. I feel like it's definitely a "Labor Day!"
