First, remove a small amount of clay from the package. Close the package so the remaining clay doesn’t dry out.
Roll the clay out on a smooth surface (I used a marble pastry board). You don’t want the clay too thin or too thick. About 1/4″ thick is what I aim for.If it’s too thick, it will take longer to dry. But if it’s too thin, the ornaments tend to curl up at the edges, and they break more easily.
Press a cookie cutter into the rolled out clay.
Pull up the clay around the cookie cutter (after pressing it into the clay), removing all the clay around the edges.
Use a drinking straw to make a hole at the top of the ornament. This is the hole for the hanger (jute twine, ribbon, or string). Press the straw all the way through the clay.
Carefully loosen the clay from the surface it was rolled out on, and transfer it to a piece of waxed paper or a cookie sheet to dry.
Allow the clay to dry undisturbed for about a day. Then turn it over and allow the other side to dry for another day. The clay will be grayish in color at first, but it whitens as it dries.
After the clay has dried and hardened, cut a piece of jute twine (or ribbon) and tie to make a hanger.
