Adventures in Sock Knitting

I am knitting my socks two-at-a-time on circs, and this weekend (while marathoning the Olympics) I turned the heels! I have not done all that much of the decreasing on the foot yet, but it feels good to be this far.

How far are you? Have you run into any parts of the pattern you can't figure out?

I'm curious what yarn you all are planning to use for Blackrose! I've sort of settled on a merino/nylon blend I bought on Etsy, which is called 'Black Coffee' and is a muted blend of browns and grays. It's a bit bigger than the average skein of sock yarn and I'm hoping it's enough to do the wristlets as well as the socks. I haven't wound it into a ball yet.

If you've already started knitting, I would like to see pictures! (Even if you haven't, I love looking at yarn and would like to see pictures of your yarn balls.)
