For this project, I used a tutorial that I found on the website Camille Styles -- here. All I needed was air dry clay and some gold paint, so I popped into the craft store to purchase some. If you don't have a lot of items at your house that would make a cool imprint in the dish, you could probably pick something up along with the clay and paint -- I used a necklace chain to make my design.
This tutorial was easy enough to follow, and actually inspired me to work more with air dry clay -- hence the brooches that I made for the shop. There's nothing much to be concerned about here, the only thing I needed more of was patience while waiting for the clay to dry out. Sometimes it's difficult to do projects that require you to wait 24 hours or more before finishing it.
