It has a happy ending:
Turns out that one of the advantages of sorting the stash is that teeny-tiny balls of handspun might appear from between the cracks. This really *is* part of the same lot as the other stuff, by the way: I never (or very rarely) end up with matching amounts of singles on the bobbin when I spin, so, when I ply, one always runs out significantly before the other. I have the habit of winding the excess singles off into a plying bracelet, and plying them together (if I'm making 2-ply), or chain plying them together for a 3-ply. Sometimes I wonder why I do this: it seems to be turning frugality into a bit of an obsession, could I ever really need those last two grams of yarn? Don't I have enough stash, really? Turns out, sometimes it really is a good idea.
This is how far I got with the gloves before running out: the cuff, thumb and hand have been knit, including a set of short rows designed to ensure that the glove's fingers all start at or near the actual base of my fingers. (A pet peeve). FO Friday?? Wait and see... ;)
