I made a Kirby chess set out of polymer clay. The idea actually came a few years ago, when I was watching my friend play chess and doodling at the same time. I ended up drawing each of the pieces as Kirby. My friend reminded me of this recently, and he told me I should actually build the chess set.
To make the pieces, I rolled balls of aluminum foil as the centers, and used polymer clay around it. The bases were polymer clay circles with nickle-sized openings in the bottom. I waited until I sculpted all the pieces to paint the faces on.
