Here's a nice write-up on on different fabric types etc:

Most interesting is Oratex:
"...Oratex is based on a woven polyester fabric, but unlike other aircraft fabric systems the weave filler, UV protection, and color coats are added at the factory..."

ie: Just pick your color, stick it on and heat-shrink it tight and done!
(I have no experience with this new stuff)
