Quiltaddiction - welcome. Lucky DH. The idea sounds great and I'm looking forward to seeing how you go forward with it.
Stenthpatric - welcome. As quiltE said, decide on a character and then let your imagination run wild. There are all sorts of techniques to use. As I noted at the very beginning, I designed Franky on graph paper and then did him out of 1" squares. There's paper piecing, a regular piecing and applique etc. Hope you join us.
kuseta - I hope you find time for your frog quilt. We'll be here when you do.
