This black fiber optic fabric is a cool and unique way to add some shine to your e-textiles project. There are optical fibers actually woven into this piece of fabric! Simply shine a bright light into the fiber bundle, which is collected at one end, and the fabric fills with little shining pinpoints. You can make the fabric nearly glow with a little bit of abrasion, just rough it up with fine sandpaper to damage the fiber and make it “leak” light. Selective abrasion is a great way to make a pattern!
