Got out the postal scale this morning to split up my ready-to-dye superwash sock yarn, found out it wasn't the incredible deal I'd thought. I'd misremembered the weight, it's a half-pound (just over 220g) instead of a full pound. So after shipping it's about the same price as if I'd ordered 2 hanks from KnitPicks, still about half the cost of handpainted yarn. And I get to play with it.
I've balled off half to be reskeined later, the other half's ready to go when I get time.
