Well, after twenty-five hours of knitting, I decided to block the Kid Mohair Wrap -- still on the needles -- and see what I've got.
This is eighteen repeats of the "crossed eyelet" stitch, which the pattern says is what is in the accompanying photo. If I added the knot-stitch border at the end now, my finished wrap would be only 53 inches long, so I can only assume that the "2 balls" in the pattern is a mistake for "3", as going by this test-blocking three balls of Kidsilk Haze will make it almost exactly 60 inches, the target length in the pattern.
Note that I could not reasonably get a 30-inch wide piece, so this is about 27 inches. Pulling it harder would of course make the length even less. It is obviously pretty fiercely blocked in the pattern's photo --
But now 60 inches seems a bit stingy for a wrap to me. If I use the fourth ball, it would be around 80 inches, which is probably too much. Is 70-75 inches a good length for a wrap? I've been going through the dresser drawers, pulling out scarves and stoles and even bath towels, and draping them around my shoulders, and still can't decide. Any advice?
