bottle cap
tab from a soda can
sea shells
tiny toys or rings from "gum ball" machines
wooden matchstick
an earring (if you have 1 that you lost the mate to)
tiny x-mas ornament or x-mas light bulb
pom-pom
a cork
Q-tip (maybe glue the cotton down first)
refrigerator magnet

You could probably find lots of inexpensive little toys and things at a yard sale.
