I was happily decreasing the gusset stitches after turning the heel when I happened to look at what I had knit on the front of the sock and noted a miscrossed cable back before the heel. Argh! Again I frogged it and fixed the problem and re-knit. This time I finished the sock. It only took 6 tries. I could have knit the two of them if I hadn't had to frog so many times.
To summarize: (my generic sock pattern)
Cuff - 2.25mm needle casting on 72 sts and following the first two rows of the Ruddington chart adding 4 knit stitches on each side of the sock.
Leg - switch to 2.5mm needles and knit 7.5"
Heel flap - Eye of partridge for 32 rows
Gussets - decrease to 70 sts.
Toe - decrease every other round to 32 sts, then every round to 26 sts.
Graft using Kitchener stitch.
