I stumbled on to the Quilting Board while looking for sites to post fabric requests or sites to respond to.
These are the ones I've found so far:
www.missingfabrics.com
www.fabrics.net
Looking for Fabrics
Fabric Requests
www.all-about-fabrics.com
Wanted Board
www.ladybuttonfabrics.com
Fabric Want Ads
www.ahmercantile.com
Fabric Finder Forum this is on a menu that goes across the page near the top
www.rjrfabrics.com

I have not posted a request to any of these sites, but I have responded to requests from the first seven sites.
I don't know how the last two work.
Hope this is helpful.
