It would be interesting to do a "sampler quilt" that had all kinds of different techniques of fabric folding, puffing, origami, yo-yos, etc. Ahhhh......My little wheels are turning!
I saw another technique where they sewed two strips of contrasting fabric together, cut them in block length strips and then inserted them into the block with the strip twist a half turn. (I'd better find a pic of that. It's hard to explain.) Anyway, they put a few twisted strips into one block and it made a cool visual, as well as textural, tactile effect.
