I added a blue circle under the white one, then stored the chocolate clay shapes in the fridge to wait for the cookies to be ready. As soon as they come out of the oven, put the chocolate discs on the hot cookies. YOU CANNOT MOVE THEM AROUND AFTER YOU PUT THEM DOWN! Make sure that you put them where you want them the first time, because the heat from the cookie will start melting the chocolate immediately.
The heat will melt the chocolate and adhere the design to the cookies. Once you put the shape on, don't touch them until they cool off completely and don't look wet any more. They'll get all melty-looking, but don't worry. Once they cool down they'll look normal and non-shiny.
The cooling could take a long time, though, possibly hours. If you want to speed things up you can put them in the fridge. The only thing to deal with then would be some slight condensation when you remove them from the fridge, so you'll have to let them sit and dry out before bagging them if that happens.
