For the Gaylaxicon dealers' room, I made stickers with drawings of dragons, other characters, and flower petals. Someone had told me people love to buy stickers, so I drew a bunch of round designs, got some round printer labels, and made a whole bunch of them. Nobody bought them (it wasn't really a furry-themed con anyway) but they were sure fun to make. I'm sure I can sell them at future events.

Here's an arrangement made from the art I printed onto the stickers.
