Here is my version of the Ridged Feather socks:
I modified the pattern from 11 sts to 8 stitches, which worked, but I had to fiddle with the centering of the pattern down the foot, etc. I did the forethought heel and it worked, but it was too much juggling with the provisional cast on and joining into the round, especially with small needles. For the 2nd sock I plan on doing the afterthought heel, then I will be able to compare techniques.
It is my best fitting sock so far.
