Last week I made my own business card holder out of bookboard and it's held up surprisingly well, even without a paper covering or acrylic finish. I was feeling inspired yesterday so I bust out the watercolors and gave it a fluid wash and then went over the whole thing with acrylic polymer clear gloss, which can be found at any art supply. At some point I may draw an intricate design on it with ink but I'm going to live with it for a while and see how I feel. I think it looks rather smart.
