I, too, have the OCD/ADD problem, but now that I'm "old" I can finally say, "So what!" I had a little help with this attitude adjustment when I was putting my units together for this same quilt! I thought I'd do the king size, so made all those units. Ended up with the smaller version & now it's waiting to be quilted. I know there are places where the same fabric is next to it's mate - So what!
