I love how super easy they were to make. I just started layering different pieces of tape across the tiles. I finished them off with a layer of modge podge on top to seal the tape and keep the ends from pulling up. This also creates a good water barrier for spills or when your cup sweats and leaves that ring of moisture. Notice those happy colors too?? Yes, in a houseful of boys I don't often get to have girly, happy things around so I made sure to go with the bright colors and fun flowery pattern.
