These are from Betz White, the caterpillar and unrequited love eyeglass case tutorials are just delightful. She has two different versions, but you can do your own thing. I think that her first version would be perfect for Valentine’s Day. This design can be done in any color combination using whatever felt and fabrics you’ve got around. Her first version (pictured) was red and she used felt balls to create the caterpillar. For this tutorial, she decided to make one up with a button caterpillar instead to show variations.
