It's actually pretty easy to follow, though I did modify it a bit. The pattern calls for a J hook, but I wanted to use my sock yarn and on the package it said to use a D hook so I used an E hook. Also, because I was using thinner yarn, I had to do more rows to make them fit my feet (I have size 10 feet). Anyway, I had to add 2 extra rows to the bottom of the sock, so round 21 is really round 23.
Also, I did not cut the yarn after chaining 12 and attaching it for the heel. I simply continued on with the barrel of the sock. When I had a complete round of gray at the top of each sock, I cut the yarn, wove in ends, and went to work on the heel. For the heel, I basically followed the instructions, but honestly, from making so many stuffed animals, I know almost instinctively how to close up a hole to my satisfaction, which is really all the heel is.
So now I have a pair of socks to wear with my boots, and it only cost me two skeins from my stash. I do not recommend these for selling, because they take way too long to make. To make the pair I spent at least 6 hours. However, they would make fairly inexpensive gifts and with good color selection, could be for both guys and gals. It would be difficult for the recipient of a pair of lovingly crocheted socks to properly appreciate the work that goes in (and it's a lot), so be careful who you bestow your masterpiece on.
I made these with Patons Kroy Socks Stripes yarn in Mulberry Stripes with an E hook.
