This last design was motivated by the desire to get rid of a set of name cards, and put everything on one card, or, the back side of one card. I used the simple Clarisworks 1.0 program to do the layout, and I printed the cards on a slightly yellowish cardboard with my old Stylewriter ink-jet printer. The result is surprisingly nice, the crispness doesn't show in these images, unfortunately.
Most laser printers can also print on thin cardboard directly.
To cut the cards, I usually just use scissors. To make really nice and sharp edges, you might want to use a real paper cutter device.
