Per GM Persida: Spun glitter refers to a fine-threaded fabric that has bits of glitter painstakingly spun into an individual thread, then that thread is incorporated into the weave. The fabric can made from wool, silk, cotton, and can be used as a thread. Silver, gold, platinum, and electrum are all very popular since they don't tarnish with washing.
