Yummy leftovers

My sister-in-law dyed some stretchy cotton for socks, then gave me the leftovers. I had thought to make sock legs out of them, making the feet out of something else. But life had other ideas. It was exactly enough yarn for my daughter's new lacy hat love, which I finished just in time to put her on a plane back to college:

Now I'm in that post-holiday pause, where I need to cast on something NOW, but so far nothing has had sticking power. I'll be starting a new pair of bamboo socks tomorrow for a co-worker (if she remembers to bring in the yarn), but what about today?

Because my daughter got into my stash rather heavily when she was home (apparently I got her all the way out of her teens without her realizing just how much yarn there actually is in this house), I now have a bag of Patons Canadiana that was going to be a sweater that is now going to be... a vest. Apparently for the above-mentioned daughter. Something close-fitting with little cap sleeves. Except that I can't find a pattern like that... ("think, think, think," tapping finger to head stuffed with fluff...)
