Well, the warning was too late for Tama and Linda; they discovered the pattern mistake on their own. But I love the resourcefulness of crocheters. Tama went ahead with round 41 and decided her blanket was perfect and didn't need the last round.
Linda finished round 40 with the extra stitches and is going to modify the remaining rounds to make it work.
They're both terrific!
I didn't get any further with mine. I frogged about 50 stitches (the first several treble clusters) and restarted the round as it's written in the pattern, but that was it.
If you haven't finished your Mini Rings yet, go ahead this next week and send/post the finished pictures.
Thanks for reading and looking.
