I finished the mystery socks on January 31:
They are nice and warm, and in shoes don't look too bad :)
I started another pair on February 1 - Socks for His Nibs, made out of the bright orange yarn I mentioned before. I wanted to do the pattern because I want to get more comfortable with flap and gusset heels, especially toe up style. I'd like to get to the point where I don't need a pattern or need to look at a reference; basically, to be as comfortable with flap and gusset as I am with short row.
I decided on a little cardigan with the cashsoft, and finished it pretty quickly. I still don't have buttons for it though, since I'm not sure any of the buttons in my box really work with the oatmeal color of the yarn. It is very soft and snuggly though! Now I need to decide whether I want to go with socks or a blanket for the accompanying gift.
