In among Joyce’s no-longer-needed craft stash was a significant number of bottles of Queen brand food dye. Eventually I also found instructions for using it to rainbow dye yarn. In my opinion, a much better use than dyeing food with it! I chose some pale oatmeal handspun yarn and tried it out.
I am sure it was the Joyce connection—it wanted to be hats. I knit one beanie.
Then another and another.
And eventually there was a hat. And another hat, and another. Until–I ran out of yarn. But not food dye!
