I never really thought of it as a fandom, but I crochet. A lot. This is my favorite thing I’ve made. It was a gift for a friend, who died about 5 years ago, so he came back to stay with me. He was the Star Wars fan, far more than I am, so I can’t really claim that fandom. I just obsessively tie little knots in string. His clothes come off, but it’s not very dignified for a Jedi, so I won’t show that.
I also like to ferment foods, but I’m still just trying to figure out what I’m doing, unlike some of the real microbe pros around here. I’ve learned a lot in the Fermenting thread.
