I think it's Berroco sock yarn of some sort?
Anyway, I picked it up again last week, and I did a few more rows. No pattern, or, rather, it's one I made up.
I took a good look at it today.
The stripes of it completely obscure the lace pattern. That's a problem.
It's also over six feet long, which is ridiculous - because blocking will put at LEAST another foot on it.
So I frogged it. One more UFO, done!
