I found some great videos about traditional paper and parchment making techniques. The first illustrates the paper making process. Paper was not used as often as parchment because it isn't as durable, and it was a new technology (so obviously the old guard didn't like it).
This second video is a great illustration of the overall manuscript making process, from parchment to binding.
