I do these. I use two coats Mod Podge inside and out. I glue the wick tab to a penny with liquid nails and glue the penny (with liquid nails) to the bottom of the pot, covering the hole. I also put a couple of coats of Mod Podge around the penny to seal the opening between the pot and the penny. I spray paint mine and use stamps on the outside. They are a bit of work, but I do them mostly cause they're just so stinkin' cute! HTH, Lisa
