I spent I don't know how long gathering up my laceweight from my studio, random bags, project bags, et al. And then I sorted them roughly by color. There are ten of them.
Three in that bookcase. The other two shoe boxes are filled with sock-weight yarn.
Six in bins on the bed, at least for the next hour or so. And one more in my studio, filled entirely with bright yellow Gloss Lace yarn, the rest of which is in one of those boxes. While I was sorting, I found a ball of black Rowan Fine Lace like I'm using for the darker green half of the doll vest.
I really could use a couple more shoe boxes, but this will do for now. This is going to make sweater design ever so much easier. No idea why I didn't think of it sooner. I've had my yarn sorted by weight for ten years or more. (Line upon line, precept upon precept, here a little, there a stash.)
