Jaci, ding, ding, ding! You WIN the prize--if there was one, of course, and there isn't.. In proofing this I found that discrepancy too and we decided not to change it, figuring no one would notice. Yes, they are exactly the same pieces, just from two different fabrics, and yes, they should be the same size. I couldn't ask Sue why she did it this way, but you can use either measurement for those squares. Good catch!
