I've made numerous attempts to successfully hand paint scenics on plastic cups and dinnerware to make them both safe and durable to use. In most cases, the paint faded quickly or gradually chipped off even though it was sealed. Unlike glass paint, you can't bake the paint on in the oven! I then discovered how to preserve the art and make it dishwasher safe by using several coats of Mod Podge as a sealer. Not only does it do an exceptional job, but the sealed colors remain as bright and vibrant as the day they were originally painted despite time and heavy use. I recently cleaned out my summer stash of plastic drinkware to get ready for the season ahead. Several glasses and cups were just a bit scratched but not cracked so I decided to try painting them for a fresh new look. Here's my tropical plastic stemware step-by-step project and I hope you'll give it a try! The scenes were painted "freestyle" without a pattern but you can use a light pencil to draw guidelines over the gesso coat if you're not confidant enough to just go for it!
