Lovely quilt. I think you did a great job chopping it up and turning it into something different.
I've never tried basting on the wall. . . maybe I'll give it a shot. We live in a small condo and the carpet is really frustrating to baste on. I need to find a better option and spray basting is out due to family members with asthma. I'd probably get more quilts done if basting wasn't so annoying. I have three tops waiting for completion now.
