Oh, what lovely fabrics!
I like to make quilts out of various squares, when I just want to show off the fabric. I do multiples of the smallest block size so they can all fit together (so maybe I'd do a blend of 2", 4" & 8" together; and if I really like the fabric I'd probably leave a block or two up to 10" or 12"), and I usually sketch it out on graph paper to make sure I have a sensible way to assemble it. It's pretty simple, sews up fast, and leaves enough fabric intact that I can still enjoy the original patterns.
