Spacing them out sounds like a good idea, I'm going to look for some ideas on the net. I also thought about arranging them into flowers on a back ground block, maybe just a center and one "ring", and then using a smallish zigzag between each hexagon where they would normally be stitched together. That would attach them to the back ground and possibly make the uneven sides less noticeable. Would that work? I do still like the idea of spacing them and adding the rick rack.
Granny9 these are paper pieced so there's not a good way to recut them, but thank you for the thought.
