It seems a lot of my WIPs are socks. I have a lock of sock sized needle sets, and sock yarn is easy to buy, so it's easy for me to cast on when I buy new sock yarn!
I did finish the Malabrigo socks I had going, which freed up another set of needles...
currently I have:
Green Tanis purple label cashmere blend socks.
These were originally going to be for my FIL, but it turns out he doesn't really like the cashmere blends. I mean, he likes how they feel, but he doesn't like that they wear out quicker than other blends. I told him it doesn't matter, I'd just make him more, but no, he wants his socks to last forever. The fact that he doesn't really want these makes a couple of other guys I know quite happy - there is a bidding war going on for them!
Then there's the sport weight String Theory socks:
I love these, and will keep them, even though there is interest from other parties.
My sadly neglected Witches Britches socks.
I will probably knit these int he car on the way to the cottage next weekend - they won't take long to finish.
I do have another pair - the blue fluorescent Regia socks - they must still be in my purse - they're gorgeous!
