Here is what I have so far for the Dresden Plate. I'm thinking something like the drawing for the background, something dark, but I don't know what yet. I was going to fill in the indents with the button background, but I kind of like the in and out of the current set up. I think I'm going to do something for the border. I'll play with that.
