It starts at the bottom, which is kind of fiddly (just sort of difficult to arrange the four cast-on stitches on doublepointed needles), but once I'd done a few rows and got it large enough that it would fit on a short circular needle, it's going very quickly. We're going to go away for the weekend on a little road trip to Branson, so it should make good car knitting, I think. Assuming I don't finish it before then.
