Guys, for webbing of all sizes colors and textures, try  Seattle Fabric:

http://www.seattle2000.com/seattlefabrics/

This place has a huge selection of that sort of thing.  It's at 87th and
Aurora in Seattle but they also do mail order.  Their main business is
supplying backpack and outdoor equipment manufacturers, and they'll send
samples.
