Coasters, if I can get the darn things to stay flat when they dry (they're hand-built rather than thrown). Also spoon rests (which are thrown) and a couple of sake sets - the sake bottles are too big to be considered space fillers IMO, but the cups are itty bitty.
I make handbuilt coasters. After I cut them out, I smack 'em down on the table. Then put on wheel for a quick smoothing of the edge. They stay flat.
