I just used high quality laser paper with a nice gloss for the whole thing. It looked really good when completed and the colours don't rub off or anything. As for how I make them, well I have a template now for the design stage of it. Printing it and cutting it out isn't too hard. The worst part is finding a good printer that lines up the images well when you print front to back. You need both sides of the page to be in the exact same spot for when you cut them out. It took some trial and error, but I eventually found a good printer at the local print shop.
