: ... at seattlefabrics.com has a variety of colors and thicknesses, but sit
: down before you ask about prices. They sell it by the running inch!!

Seattle Fabrics tends to be on the spendy side of the
retail sources for outdoor fabrics. Is it because they're
in such a comfortable neighborhood? Alternatively try:

www.justmakeit.com (in Alberta--great catalog)
www.owfinc.com (great prices and service)

And some others that do mail catalogs: Quest Outfitters in Florida, and
Rain Shed in Oregon. A search should turn up both--I'm away from my
info.
