Well, thanks to advice from Shetha on the knitblogs list, I just made the necessary increase and decreases to make bmy socks each have 60 stitches, and knit bravely on! They seem to be doing okay with that, there are only slight varyations in the patterns and I don't think the fit is going to be affected. Now I just have to figure out the heel....all the patterns for toe-up socks seem to just say "turn heel" and nothing more, so I'm going to have to search for a pattern that is a little more explanitory.
I had to go to the hospital for an echocardiogram (nothing serious, just checking something out) and I knew there would be waiting involved so I brought my socks to work on. A lady who was also waiting to have an echo started asking me about them.....she thought I was just amazing knitting all those fancy patterns into the socks without even looking at my fingers, so I had to tell her about the wonder that is self-patterning yarn. She had knit in the past but not since this yarn had been available. So we started talking about knitting and crochet.....she created by sight, not pattern, just sort of making it up as she goes along, which is pretty neat. I love how knitting can spark conversation with all sorts of people in random places!
