This post is a little late. But this was a last minute quick idea for count down cups with foamies. Simply take numbered foamies or felties and stick them on your campaign glasses. This will also work as cup markers so your guest can identify their cups. I did two sets, one with white foamies and the other I glue-sticked the surface dipped in purple glitter. The foamies come out pretty cleanly from the glass cups also.
