I've been looking for inspiration for the layout of my future I Spy quilt. Crafterhours has a Pinterest board dedicated to quilt designs and I also googled "charm squares" for additional ideas.
I like the layout of this one. It's bright and fun. I could either cut up the smaller print squares received from the swap for the tiny rectangles or I could use solids/prints already in my stash.
This next one is similar to the one above, but it has fewer white sashings between the prints. The pattern uses 38 charm squares, but I think I'd want a bigger quilt, so maybe I'd need an extra row or two?
