I did 12 rounds on this one before I realized I'd been reading the pattern incorrectly. So I pulled it out down to the purple round (here, before the red outer round) and will stiffen or mount it. And then try again to read the pattern correctly! No worries. I think the fun for me right now is in stitching of it, not in the completed project, so I don't mind pulling out rows, just like that ripple afghan earlier.
