Stash yarn bought on sale at Stitch House. Sock yarn that was made from ground up shells so that it has antibacterial properties. I could never get it to work in the CSM before so I dyed it with Kool Aid, which changed it’s properties slightly and it worked very well. It was meant to be a hat, however, I turned the work inside out not realizing that I was closing a tube. It turned out beautifully though and had I known that I would have been using it has a cowl instead of a hat, I would have used a Kitchener’s stitch to close instead of a whip because it shows.
