This pendant was made with a 1.5 inch round wooden piece from an old Bottle Tops game. A collage image that I created was decoupaged onto the game piece and varnished for a smooth and water resistant surface. The image features a skull from a Cezanne painting, butterfly wings and vintage mushrooms.
Decoupaging is so easy to do. If you find an image you like or create one of your own, you can attach it to almost anything. You can buy 1.5" wooden discs at the craft store if you are not lucky enough to find game pieces you can alter.
If you don't want to make your own pendant, this skull with mushrooms designed pendant is listed in my Etsy Store.
