From spookydonuts on Instructables:
At about $150 a yard and with plenty of cutting limitations, fiber optic fabric on the market isn’t the most accessible material. But with your own fiber optic filament, tulle, and LEDs, you can create your own in any shape for a fraction of the price.
The tulle and fiber optic combination in this Instructable is very translucent. The simplest way to add it to a project would be as a top layer over a more opaque fabric. When designing your project, remember that your fiber tips will all need to feed into a light source, and most light will be emitted at the opposite end. As long as you can design something with enough support for the lights and battery pack, and ensure that the fibers have a light source, you can create any size and shape you want!
