Hey kittens! (And kats...)

I have bit of a pickle. I am looking for blueprint paper - the kind which is used in ammonia blueprinting machines. I'm not sure of the exact name, but it's photo-sensitive and thus if the paper is left in the light, it goes bad.

Searching ebay, I only came up with one auction where it was, alas, an open box - thus rubbish.

Do any of you guys happen to know where I can find some, either online on in the Los Angeles area? OR! Do any of you crafty girls'n'guys happen to work or go to school where blueprint paper is available and could perhaps snag some for me?

The paper is being used for a project for my college portfolio (scream) and I can't seem to find some anywhere! I'm at a loss! I would be *so* grateful if you guys could tell me where to find some, and hopefully on the side of cheap.

Thanks!
