That's not a mistake off to the left, it just wadded up on the couch. I did discover a bad mistake near the bind off area, it started to unravel a bit. I used a tapestry needle and spare yarn and carefully fixed it (it aint pretty but it works.)
This is so very very nice! A substantial shawl like this is attractive, and also useful cuz it's not so fragile! This is a shawl a woman can use every day, every week, every month, year after year! Good job!
