I decided to use the middle strip to begin with. Parts of the others might join in eventually. We'll see. So here's how those blocks went together after they were liberated from the strip, chopped up, and stitched back together freestyle.
Stuck with purple for the Round 2 crumbs. Since the middle was already pretty crumb-ly,
I tried to contain it with a small orange strip but added a few orange teeth in the border just for fun.
Waiting on Round 3 to trim it up. Can't wait to see what's next!
