We have four large fabric stores here in Portland, Oregon, that carry a variety of fabric, they all have several types of nylon in Blaze Orange and Florescent Orange. Also sometimes, Pendleton Woolen Mills has had some Hunters Orange taffeta available. I bought a 10 yard chunk last year, to make doggie vests out of. I would think Quest Fabric and Seattle Fabric would also have the orange fabric available. Pendleton, just charges the shipping costs that the post offices charges them.
