Not to toot my own horn, but I sorta think mine turned out better. I haven't actually seen the Pottery Barn ones in person, but I am sure "German Glitter Glass" means "Fancy Named Glitter That is Going to Cost You $19.00 a Piece."
The supply list was easy. Styrofoam skulls of any size; mine are about 4 inches in height. Spray adhesive glue. Assorted color glitter. Craft paint in the same color as your glitter. I also needed a paint brush as well as a pair of rubber gloves (the think kitchen kind worked well.) It cost under $20.00 at Michael's.
First, paint the skulls in whatever color you like and allow them to dry. You are only looking for minimal coverage so no white shows.
Second, spray small sections of the skulls with the spray adhesive. Wear gloves and avoid gluing your hand like I did. That adhesive is brutal! Also, please spray outside so you don't give your friends and family cancer. Thank you.
Third, quickly cover that section in glitter.
Repeat until fabulous.
Please keep this in mind, I am working with my rather sad back-up camera because my good camera died. Also, glitter is damn hard to photograph!
