I used Acoustical Solutions a couple of years ago [ http://www.acousticalsolutions.com/ ]. They sent me sample that are very helpful, especially for the WAF.
Also, I have these book marked for a future project, but have not used them:
http://www.simplyspeakers.com/11speakergrills.htm
http://www.speakerworks.net/grill_cloth.html
http://www.new-foam.com/fabric1.asp
These are old bookmarks so the fact that they are still there implies they are legit. You can also try Parts Express, Radio Shack, or JoAnnes.
Personally, I would call Acoustical Solutions and ask for some advice, and some samples. They are very professional and we in HT/Audio are small customers to them [they do Highway soundproofing too], but they spent some time with me and their stuff made my installation really good looking.
Keep in mind that some grill cloth is not very stretchable. Sometimes this is good, but sometimes it makes it hard to work with (corners).
All this stuff is Internet/Mail Order, aside from JoAnne Fabrics, I don't know where else you would turn. I hope this helps a little.
Good Luck,
Dave
