Thanks, Pam and Sauki for your comments. I don't have a plain brown but found one with tiny flowers that pick up the peach and blue in the A/B combo but doesn't have any green in it. On the following photo I switched E & F as recommended and have put the brown in the pic. I'm close to giving up and waiting for the next MQ when Judy is well, but I hate to waste the blocks I've already assembled.
