Begin by rolling out about a cup of clay to a 1/4-inch thickness.* (I recommend working on a silicone mat or wax paper to prevent the dough from sticking to your surface.)
Press your cookie cutter into the rolled-out clay. With your cookie cutter still in place, press the stamp inside the cookie cutter. Apply even pressure to transfer the design.
Remove the stamp. Remove the cookie cutter. Then transfer the clay cutout to a parchment-lined baking sheet.
Use a toothpick to create a hole in the cutout. Ensure the hole is large enough to fit a piece of twine, ribbon, or ornament hook.**
Repeat the above process with the remaining clay or until you've created your desired number of ornaments.
Bake at 275 degrees F for about 17 minutes. (This is the time suggested for 1/4-inch thick ornaments. If your thickness varies, adjust the baking time according to the package directions.)
Remove from the oven and allow to cool completely on the baking sheet.
Thread the hole with twine, ribbon, or an ornament hook.
Hang on your tree, decorate a package, or create a garland.
Notes
*While it's not necessary, I purchased THIS rolling pin for the project. (It comes with a silicone mat mentioned above.) What I love about this rolling pin is that it can be customized to roll a perfectly consistent thickness. It was a game changer and made this process really simple.** If you need to enlarge your hole after baking, this can be done with a power drill and drill bit.
