Take it away Natalie:
1. Turn the glass coaster upside down and randomly place several removable round stickers on top. If you are not sure they are removable, test it on another piece of glass first, let it sit for several minutes and try peeling off. If residue remains on the glass, you may need to use different stickers.
2. In a well-ventilated area, place the coaster onto a newspaper-covered surface with the stickered side facing up and spray paint over it until it is completely covered. Apply a couple thin coats and let dry between each coat. Make sure to not over-paint to avoid the paint from seeping through under the stickers.
3. Once the paint has completely dried, remove the stickers. Be extra careful not to peel off any of the paint on the glass.
4. Grab your second spray paint color and add another layer of paint on the back of the coaster to create the polka dot effect. Let dry thoroughly.
5. To avoid the paint from chipping and to add a finishing gloss, spray craft sealer on your painted surface following the manufacturer’s directions. Adding a sealer also allows you to wash the coaster if needed.
