Well, the lace scarf is going... slowly. Doesn't help that I forgot to bring the pattern with me today, so can't do anything on it. Wish I had remembered to take a picture, too, but that seems to be pretty standard.
Also unhelpful: Addi turbos. Blunty McNopoints and I are not getting along at all. It takes two hours for me to finish one inch of lace. For contrast: Tubey (which had four and a half times the number of stitches in an inch*) took 50 minutes/inch.
So I asked the wonderful and helpful husband if he wouldn't mind running to the LYS to replace my bamboo needles for me. No problem, he said, just send him what I needed. And I did! I was very careful to specify that I needed US size 2, not 2mm, and to ask the clerk if he wasn't sure of the difference. And he very nicely brought me home a lovely Clover bamboo circular, size US2. When I go to knit onto the new needles, they're huge. What size am I actually using? US0, aka 2mm, of course. Well, he wanted to get out of the house anyway, right? (He went back again last night, but see above re: no pattern, so I haven't actually knit with them yet.)
I did find a very neat solution to the knitting-both-ends-at-once thing. And it was completely by accident. When I was going to knit the other scarf, I chickened out on the laceweight and decided to use it doubled. My solution to that was to stick both ends of the hank in the winder and wind them simultaneously towards the middle. (Don't try this at home without at least one extra pair of arms.) Now I'm knitting single-stranded - but both ends are at the center of my center-pull ball! I've been going slowly, true, but I haven't had any real twisting or tangling issues, so I think it's been a success and it's definitely something I'd do again if I needed to work from both ends of a length of yarn.
*Not actually true, upon reflection. This is 14 rows/inch and Tubey was... 7, I think. So only a bit more than two times as many stitches, but it still took less than half the time, and I still feel justified in saying, "lace! GAH!"
