Now I'm thinking lace is my best option. Lace edges, particularly on the cuffs, would really take advantage of the belled sleeves. But what lace? I have a few ideas, so I just have to start swatching, I guess.
Um, I just tried taking pictures of the first five rows of a sleeve so you could see the mini cable idea I was trying out, but the old camera (which can safely travel in my knitting bag, as opposed to the new, very fahncy, digital SLR) was pretty useless that close up. And the flash blew out any detail, while the non-flash version of the shot had far too long an exposure time to be steady. I'll get pictures sorted out for this ol' blog someday.
So, lace, yes. Now I need something that will work in the round over 60 stitches for the sleeves. There could be a few odd stitches left at the underside, I suppose.
I'm starting to think that I might just do a provisional cast-on and figure out the edgings later. But that's not nearly as much fun!
