I can't imagine what you thought might be wrong with it, and I especially like the way you've worked in some four-patch blocks. The only thing you could possibly do wrong is wash it in your home washing machine, and that would be a lot worse for the machine and plumbing than for the quilt! I took a large one to the local laundromat and asked the attendant if there would be any problem with it, and he said to go ahead. They have special filters on the plumbing, and the oversized machines are very sturdy.
