SuzSLO, thank you for following up! I could have sworn I cut 4 1/4" squares for clue 2, but my directions, which I printed out on the clue day, also say what you indicated! Thank you for straightening me out! I was in such a tizzy about it, LOL.

Thank you, as well, Playhiker. (We may all have our posts deleted since we are mentioning actual sizes and quoting the mystery text, but I do thank you both for your help!)
