Single Sock Syndrome. Most sock knitters I know have been afflicted with this at some point or another. You make one sock, and then... you're over it. You're either tired of the pattern, or you've forgotten to write down how many rows it took to get the leg up to 6 inches, so... you're left with a single sock, to lose in a drawer somewhere, totally useless. But you spent a lot of time on that sock, and the yarn was really great and now you have another ball leftover. What are you going to do with that one? So it all just sits there, wasted.
Well, I don't think that's going to happen to me any more. I've had this book for a long time, and finally was able to give it a try when Jessie asked me to make her a pair of green socks (she wants me to put eyes and smiley faces on them, too, but we'll have to see about that...). It worked great! I used size #1 Options Harmony Wood fixed circular needles from KnitPicks in the 40" length, and loved every minute of my knitting. And when I was done, I was truly *done.* With both socks. At the same time. And Jessie could wear them right away, and they fit great! And with the second book, Toe-Up 2-at-a-Time Socks, you've got every single pattern contingency covered. Amazon even offers the book on Kindle! No more excuses for SSS, unless you're knitting for a one-legged person, in which case, I meant no offense.
