The Great Pumpkin

lots of towns/citys have a tandy guy/distributor (used to be like tupperware for guys, and anybodycould sell it)
check your yellow pages, maybe you'll get lucky.

also talk to peeps in the area that make saddle bags for motorcycles. most of em will sell you a square foot off cut. surplus fabric stores might also have what ya need.
tandy is your best bet though.

i used 11oz vegitable tanned leather (it was going on my face and all)
