Although it took me a week to finish these mitts, knitting a few rows here and there, you could easily manage them in a couple of tv binge-watching nights on the sofa. The pattern, Ice Scrapers, is fun but easily memorized. If you've already purchased it, make sure you get the updated version, as Amy has just tweaked it to make the directions for the thumb parts a bit easier to follow.
I knit my version in Plucky Cashmere Sport, and although that may seem a bit splurgy (and it was!), I used about half a skein. You could get two pair out of a skein, especially if you did one pair a bit shorter. I might have done mine an inch or so shorter before separating for the thumbs in any event, so this seems like a keeper of an idea to me.
Everyone needs a few quick knits in their tool kit for gift-giving, or, as in my case, for cold hands when your family swipes your gloves. This pattern is definitely a keeper.
