Bumper sticker paper ... where do you order it?

I want to make my own bumper stickers (just for me). I have an Epson Stylus C84 (it prints dynamite color prints of pictures taken with my hubby's Canon Rebel Digital).

What I want to know is ... where do you order the bumpersticker sheets/stock (you know, like you order sheets of labels .. so that you can make your own labels)? I can't find such stock at Office Depot, Staples, or Frye's. Any ideas? Some DUers are made them and sell them at cafepress.com.

I've done business with them several times and have always been satisfied:

communities have one within a reasonable distance to supply to all the commercial printing houses, of al sizes. Around here we have Kelly Paper, for one, but I don't know if they are a chain. Try "paper" in the yellow pages. If that doesn't help, call some local printers and ask them where they buy their label stock or paper. You don't need to be a printer to buy from these sources as a rule. They won't give you the wholesale price unless you have a resale license. This is much cheaper than if you track it down in an office supply place. It may come in small packages, but may be only in larger quaantities. You need to find out if the paper compamy you contact has label stock, in what size, if it will work for your type of printer, if it will feed through your type of printer. That's all I can think of at the moment. Yes, I'm a graphic designer.

I'll try Kelly Paper. I want to learn to make my own, not go through a site that will make them for me.
