DIY coasters w/ your lily planner pages when the year is over! Mod Podge the paper onto ceramic tiles. Spray with high gloss acrylic protective spray (at least 3 coats). Hot glue felt circles to bottom of tiles.
Make your own coasters- tiles, adhere picture/paper to tile with Mod Podge and let dry; Spray a coat of clear spray paint and let dry; attach felt pads to the bottom. Doesn't have to be beer coaster either!
For me its the maps, I love maps 8 Mod Podge DIY Coaster Projects - This lady is the "queen" of Mod Podge and she does offer the gentle reminder at the beginning to use an outdoor sealer to make them waterproof- it must be done with coaster projects.
