I found the pattern on Ravelry. It's Traveler Socks on D-Made. I started them Monday night and finished them Saturday. Worsted weight yarn on size 5 needles helped. A lot.
I have never done a crochet provisional cast on before. The first sock I did it wrong because I had to cut the crochet chain out of there. For the second, I went to You Tube and looked at some tutorials. It is amazing to me the "how to" videos you can find on there. Really cool. I followed this one and the second cast on was a breeze.
The other thing I like about this pattern is that the cable patten is written out. I have a really hard time following charted cables.
Kiddo picked out the yarn color. I wanted Lion Brande Wool-ease because I thought that it would not be too hot and the inclusion of the poly might help them wear better.
These are really ugly until you put them on your feet. Then they are amazing.
