I was trying to resist making more, I really was. I didn't want to start another project til others are finished, but I couldn't help myself.
Iron-on interfacing in place of fleece/batting would be an interesting thing to try. It would add a little bit of structure and strength while being easier to deal with. Then I could stitch these hexagons up into a nice little bag of some sort.
I want to make a quilt of these. I'd make the hexagons bigger and attempt to get them to play nicely with the batting so I could make a gorgeous double-sided quilt. Entertaining the idea makes me happy.
