About 15 years ago, maybe even longer, I discovered the joys of Fimo and Sculpey. You can use this bakeable plasticine modeling clay to make miniature images, millefiore beads, and that’s what most people do with it. They make jewelry. I can’t think why I decided to make slugs instead, but I did. They were easy to make, a little weird, contrarian, and before I knew it, a friend had given me a book titled “The Little Greenish-Brown Book of Slugs” and I was gleefully quoting from it until I could clear a room in 20 seconds.
