I made a replacement dog bed liner for my bff using some fluorescent orange fleece I got on sale at Joann's. You can't see it with the naked eye, but there are millions of tiny pieces of that stuff all over my house. I know because I had an old kitty, and I used a black light flashlight to find accidents on the carpets. Well, holy flashing fibers, Batman, those little tiny fibers really do "glow in the dark!" So, good luck with trying to corral all the fibers from when you cut that fleece.
