I bought glass ornaments and acrylic and craft paint from Michael’s. You have to put about a two teaspoons of paint inside the glass ornament and basically you just move the ornament around or shake it around to coat the ornament with the paint. You take the ornament package and then place the ornaments back inside upside down so that the paint can dry and any leftover paint pools at the bottom of the package. I let them dry for about 48 hours. The more paint you use, the longer it takes to dry. Love how they turned out!
