Thanks, Sally. I agree that the sashing unifies the jumble of colors, especially since I lucked out and found that batik fabric that picks up several of the brighter tones.
I haven't seen where it will hang in Town Hall, but that's temporary. The person I'm making it for plans to take it home after it's taken down, so I'd better stick to queen-size, I guess.
Good luck on your tee-shirt quilt too!
