Apparently the lack of actual markings on the sleeve isn't a big deal to the author, which baffles me a bit, since there were two comments (mine and another woman's) mentioning it. Heather provided a nice "further illustration" to show how to do the sleeve top, but she never said, "Yeah, we didn't put anything there and then made it sound like we had! Sorry that I made you unfold that #$#@$!!!! road map of a pattern THREE TIMES to look for what did not exist. My bad."
BUT I have bought more sale fabric (1.99/yard, baby) to try again, and will stop by my LFS, Sewing by the Sea, for tracing material and lighter yarn and needles. I'd be happy to have an actual garment at the end of this, but it's kind of fun going into the process thinking, "Maybe, maybe not." Freeing, kind of!
