Mittens knit up so fast.
Especially with a good audiobook to keep you occupied ... This is one evening's worth of knitting. A cuff, the wrist up to where the thumb goes (that white bit gets pulled out and a thumb inserted), and almost to the point of decreasing the top of the hand.
I started these last night because the lovely sweater I'm working on for a friend has gotten to the complicated cables at the hem, too much counting to do anything else at the same time, and I was really tired, so I doubted my counting skills.
Mittens are mindless knitting, which is exactly what I needed. I should do this more often.
