These coasters from here are made with printed paper and napkins! She gives a great tutorial too. I would never think to use Santa napkins or print something from my printer and mod podge it onto a coaster. And the tiles are so cheap too. She used white tiles for these. Just make sure you spray the top of the tile with acrylic sealer after the mod podge is totally dry to protect your design.
You could also try using gift wrap too!
