I just received a very nice email from Kathy, the owner of Material Obsession. She said this quilt is called "Fractured," and they sell the pattern for it on their website! They also have a pattern called "Stash Eater," which is another great quilt. I wish I'd known about the pattern at the time I was making this. It would have made things a lot easier. I hope everyone will go straight to MO's wonderful website and buy this pattern right now!
