Membrane Thread Paper.

Not paper as in paper used to make membrane threads, but a paper about membrane threads - Caroline Solazzo, Cristina Scibè and a couple more researchers have published a paper about their work on membrane gilt threads. It can be found in "Nature", and to my great delight, it's open access.
