Just when I thought my portraits were at the wacky end of the pet art spectrum, I discovered jewelry made of hair balls. Not the kind kitties cough up, but ones you make from fur you collect from your shedding pet. There are great step-by-step directions on Instructables. I enjoyed reading the comments too. Somewhere out there, there’s a person brushing their gerbil, trying to get enough fur to make a bracelet.
