Fabric/materials sources/best experience

Most likely already a thread on this but didn't see a recent one in a quick search.

I'm familiar with a few of the usual sources for fabric/materials for DIY gear, i.e. RainShed, OutdoorWildernessFabric, Seattle fabrics.

With which sources have folks had the best experience? Price, service, knowledge, selection, volume, web presence, etc.

Thanks for any feedback,

Gil

P.S. Trolls welcome

I would check BackpackingLight, found it last week when researching types Cordura fabric.

It's been quite a while, but OWF was significantly cheaper and did me right. I also had a wholesale license.
