Something that might be useful for those having trouble finding the vellum paper at Staples: if you have an art supply store anywhere near you, try looking there for "Design Vellum". The brand I'm using is Clearprint and it comes in a pad of 50 sheets, 11X17" - so you do need to cut each sheet in half before you put it through the printer. I'm using it because I happen to have it left over from the drafting classes I took a couple of years ago.
I have no idea what the price of it would be. Here's a link to the company's website:

Which tells me that the paper I'm using is 16-pound, and that it comes in a variety of sizes :)
