These things are cool! They’re just re-inforced cardboard tubes that are designed to hold a small WIP like socks on DPNs. I’d been waiting for my LYS to get something like the Knitzi wooden sock holders, but these are way cheaper. $9 for a pack of two! They fit needles from 6-10 inches in length.
I have at least 4 socks in progress, and I’ll no longer have needles poking holes in my various bags! :yay:
Oh, they were from nancysknitknacks.com.
