There was a 4-letter word in the pattern instructions that I missed - TURN.
Apparently, when you "work in the round" in crochet, you don't go round and round and round.
Not in this pattern anyway.
The instructions wanted me to go round one row, then stop, TURN, and go back the other way for the next row.
I missed that 4-letter word.
I've already frogged back once so I've decided I don't mind that there is a boo-boo and I'm going to continue and see where it takes me.
And so this project continues ....
