A belated follow-up:
I'm able to create custom acrylic templates through ponoko.com, and I've made templates for Penrose tilings. I'm looking for a few brave and crazy quilters who might be interested in helping beta test the pieces. I can make the pieces available for purchase on ponoko, with zero kickback to me. I'm hoping to keep the cost under $20.
If you're feeling brave, and are interested in doing a quilt like this for yourself, hop over to
http://domesticat.net/2011/06/seekin...crazy-quilters and get in touch. I'll make a separate post elsewhere on the board so other quilters will find this topic, too.
