Mark,
I am sorry, I read your post wrong.... I thought you had good hands, just wanted to keep them occupied. Since I now read that you have trouble with them, the calligraphy would be out. My Mom used to crochet, but now that she is 82, and her hands are stiff with arthritis, she can not do it any longer, so I don't think that would be a good thing to try to learn.

I do think you could try origami - maybe not the most difficult ones, but quite a bit of it.

Sorry I didn't understand your post correctly.

Jules
