Oh I just love this! I started working on one for my daughter. We are using scraps from her grandmother's fabric stash. We have large enough pieces to get four hexis per print. My daughter wanted it totally random, so that's what she's getting. Very difficult for me, I hoped she'd let me put them together like you've done lol. I'm showing her yours and I know she'll love it but I have nearly 1/4 of them sewn so it's to late for her to tell me she wants a pattern lol.
