Oh dear! I just made a silly big mistake too. I made the blocks too big and didn't know until I spread it out on the bed and it was dragging waaay over the bed and on the floor everywhere. I've set it aside, but it's taken me a while to get over being so upset...like 6 months. But now that I've decided what to do, I'm ready to pick it up again. So, don't rush deciding what to do, but use your time looking around for ideas about what to do.
