What’s strange, is I’d never seen an adult Carpet Beetle around the house. So when I googled them I thought I was clean. Then I saw the picture of the larvae, and that’s when I knew I was screwed.
The Cascade 220 is a goner, there’s pretty much no way I can knit with that. I have hope for the sock yarn, though. It’s just 3 broken strands and a 4th that is held together with less than a ply. (Unless there’s hidden damage, of course.) I think they really preferred the taste of the Cascade 220, though.
