Thanks so much for this post! I'm working on an Oddball Pet Snuggle and realized about 3 rows in, that I'd made a mistake. (I've never really "frogged" knitting before, just started over, b/c I was too afraid to have dropped stitches!)
I was working on it on my lunch hour, and I did it exactly as you described! Took me a little while, but I got it. I think I was as proud of my frogging as I was at learning to knit on circs.
(Incidentally, frogging is much, much, MUCH simpler in crocheting.)
