We won't even talk about the first frogging incident, which was due to thinking I was too cool to knit a gauge swatch.
Anyhoo, after realizing I was getting 8 stitches per inch, I cast on 68 and happily knit away, the cuff and the leg were without incident. I knit in my waste yarn where I would insert my afterthought heel, and then consulted my beginner sock book to see what was next. "Continue in pattern straight to the toe" it said. Awesome. Feeling quite smug about how neat and non-stripe-disruptive my afterthought heel was going to look and how clever I am for thinking of doing it this way, I knit 8" from the waste yarn and started decreasing for the toe. I have to admit, it looked a bit long, but I didn't dwell on it. Something told me not to close the toe until after I completed the heel. In fact, the more that I thought about it, that heel was probably going to add some length to the foot... yes, it seems so obvious now. Sure enough, after finishing my smug little stripey heel, I tried on my sock and it was a good 2" too long for even my size 10 feet...Suddenly not feeling like quite as much of a sock rock star I practiced my unknitting skills for what I'm sure will not be the last time.
The good news is it fits like a dream, I love it, and I can't wait to show that second sock who is boss!
