I finished my first glove, and it FITS. Yay! The yarn didn't stripe/pattern quite how I thought it would, so it's come out looking a little odd, but after getting halfway through I wasn't going to rip it back :P
I wish I'd done a rib edging at the bottom, so it didn't roll, but again, I can't be bothered ripping it back - as my first pair of gloves, there'll be other things wrong with it, so I'll just aim to do better next time :)
