Bottle caps you can use too.lots of things work for that.cute idea

use them for the middles of the 'yo yo' flowers and then glue to a big push pin. Or put them in frames or on dowels or wire in a pot.

The covered buttons could have small glass beads, fabric paint could be used to make dots or heart(2 dots side by side & draw both down to bottom for a heart,sequins,small bits of broken jewelry,tiny sea shells, lace around edge? Weldbond is good glue as drys clear & holds well. The backs of the covered buttons might be a problem as the shank would stick out unless you cut it off. Sounds fun! Show us what you come up with!

If any are velvet..you could stick a rhinestone in the center of it..
