The medallions themselves look really labor intensive, but are not. I am using scrap clay but you can use any color or colors you choose, it might be really fun to make each layer a different color, or to use all metallic clays... ? In any case they are very easy and can be created quickly!
I hope you enjoy viewing and learning this unique and simple technique. If you have any questions please leave a comment here, and it will be answered promptly!
Also for everyone who comments they will be automatically entered to win these medallions shown in the tutorial, there are two of them and they are beautiful.
