I finished the first mitten this afternoon:
And here's a picture of it in action:
I like it and it's a quick knit, but there is no shaping and I think it pulls across the palm a bit more than I'd like. One day I'll learn how to adjust patterns, but until then I guess I have to suck it up. That's it for now. I'll post a picture of a piece of the baseball sweater once I finish the front/back (I forget which one I'm working on). I've got about 14 inches of the 17 before the arm holes. I'm making progress, kind of.
