Can I use my old dryer lint to make my own black fiberglass tissues?

No, you cannot use dryer lint to make black fiberglass tissues. Dryer lint is composed of fibers from clothing and other materials, which are not the same as the glass fibers used in fiberglass production. Fiberglass is made from fine filaments of glass that are combined with a resin to form a composite material. It requires specific manufacturing processes and materials that are not present in dryer lint. Using dryer lint for this purpose would not yield the desired strength, durability, or properties of fiberglass tissues.
