Here's a montage of mittens I've knit that I can find... Most of them have partners, except the really fancy one. The grey one is from the first pair I knit. You can see the thumb needs mending. If I can find the yarn, I can always re-knit the thumb.
Then I knit the striped ones. It's actually two pair, I made opposite stripes for the girls. I think Margaret had the green cuffs, and Amelia the pink.
The red ones were from some yarn I found at the outlet store. I've had to mend them a few times.
The green/orange ones are with large gauge needles and yarn. I think it took one hour to knit one.
Compare to the fancy one. I still need to start the 2nd one of that. It is a Latvian "Cathedral Window" design. It took many hours, but I will do the partner. The cast on and cuff are very cool.. I guess you can't see very well since I haven't blocked it yet.
I'm a bit worried about wearing them out of the house, though. I tend to lose mittens...
