Well, I get in at least an hour a day. It might be divided up. On a quiet evening I might do as much as 2 hours without stopping.
About the longest project--Do UFOs count?
I spent a month working on a sweater back this summer before I put it aside, deciding I didn't really like it or like knitting it. I have an ongoing blanket made out of squares I started last spring. And my mother's Christmas present took me a month to finish. It was the Besotted scarf, with four cable rows instead of three on 4mm needles. I haven't posted a picture yet because I need to put the fringe on it. Actually, I'm trying to decide if it needs fringe or not.
Now I am working on a vest for my MIL which I estimate will take me until probably Christmas to do. I completed the left front in 8 days, so it's going pretty quickly, but am worried about the button and neck band and armhole bands, because I've never done those before.
