I did something really dumb on my first pair of toe-up, 2-at-a-time Magic Loop socks....I misread the instructions (and they were SIMPLE instructions) for the M1R and M1L increases. This resulted in a rather decorative but impractical double row of cute little holes on both sides of the socks. Yuck.
So, I reread the instructions, kicked myself for a few minutes, frogged both socks and started again this morning. Dolt. Of course, I guess I could say that the good news is that it gave me another opportunity to practice "Judy's Magic Cast-On" and I was able to do it without watching the YouTube video this time! *pats self on back*
