Keep it simple and let the main fabric be the quilt. squares and rectagles, with some fussy cutting or if there are some super hero's which can be ouitlined, cut it out and applique it on a plain matching fabric. Since the fabric is very busy, I would do small blocks with it. I did another quilt for my grandson with dino's where I cut a large piece and used it as one block (main block) and then outlined-quilted the dino's. Came out really cute.

I messed up with my figures so some of the smaller coordinating blocks didnt' match, but he's 4 and he loves it.
