Leather is another option for initial development which doesn't involve people actually digesting large amounts of the novel produce. Perhaps there is a weaker business case for producing wool and various custom hair fibers, while synthetic alternatives have become so cheap and competitive for feel and performance. I hope the days are not too far off now, that use of non-biodegradable materials are taxed or otherwise limited enough to avoid them accumulating and potentially harming our environment, which has not included such materials over evolutionary epochs of natural development.
