Here's the latest on my Honeybee cardigan. I'm either really clever or really misguided, but I've joined the sleeves to the body without using a circular needle.
Obviously, this would be super easy on a long circular needle, but since I'm too stubborn/lazy/miserly to go buy one in the right size, I've lengthened the needle by using dpns and a smaller circular on the sleeves. There are so many extra stitches that just appear when joining sleeves like this, that it helps to have some give at the sleeves until the sleeve decreases are finished. The rest of the body doesn't mind being knit on straight needles (look at me, talking about my sweater like it is sentient. This sweater is so awesome it has developed a consciousness on its own).
It's a mess, and it's a bit cramped in places, but it seems to be working. That said, I don't really recommend this unless you're as boneheadedly stubborn as I am. :P
