Where do you like to buy your fabrics?

http://www.owfinc.com/ has fairly cheap material, I use this the most

http://www.questoutfitters.com/ is similar but I've never used it, just looked at their site

http://thru-hiker.com/materials/index.php has some state of the art materials at a little high prices, never used them though

http://www.seattlefabrics.com/ a little more expensive but they have some stuff that others don't, like polyester spinnaker fabric

just noticed you're in Western Washington, Seattle Fabric has a nice store in Seattle.

I’ve ordered from Quest Outfitters. For bulk silnylon, I’ve ordered from Noah Lamport. It’s not on their website, you have to call to find out what colors they have available.

Thanks guys! Those sites are just what I'm looking for.
