I started toying with this vintage worsted.
As I mentioned, it is not a comfy hand knit, process-wise.
I made a swatch, though, and tossed it in the laundry with a load of bedding. (Safe - many pink hues in the bedding.) One hot wash, one dry later, no fancy fulling steps, and it DID shrink up a bit, fuzz up a bit, and seems much more cozy. I'll insert the photo later. If I take one.
I can't tell you what I'm doing with it. It's a SEEEEECRET.
(Vintage yarners note: Two different labels, same yarn. I noticed that with several of the yarns passed along to me from a family friend. Wonder if it was a marketing thing. You know - Wieboldts carried one line, Sears or Goldblatts carried the other, both yarns from the same manufacturer....)
