Wow, you guys, thanks!! I printed out Silver's chart, and what the rest of you are saying makes sense. Since I have knit most of one sock (and then frogged it), I understand about the heel and all of that.
As for frogging the one I almost had done ... I used The Sock Calculator, and I can't recommend the pattern generated from that. It was *enormous*. I have since switched to the pattern from The Knitter's Handy Book of Patterns
, and it seems much more reasonably sized. (The sock calculator told me to cast on 60 stitches, while the book is coming out to only 44.)
Now, I found out that my MIL wants a pair of black mittens for Christmas, and I SO want to knit them for her. I haven't made mittens yet, so I'm a little nervous to make my first mittens as a Christmas gift. Perhaps I could buy a pair as backup.
