I spray painted the metal lids with black spray paint. When those were dry I looped some velvet and glued that on the back and then covered the entire back with a felt cirlce.
Finally when they were all dried I brushed on some Glossy Mod Podge and beaded them with Diamond Glitter Fabric Paint.
I'm really proud of how these turned out and can't wait to see them on the Christmas tree.
These paper ball ornaments were based on another tutorial I found and was easy enough that my youngest helped me make all ten of them. The tutorial can be found here.
