Start by rolling a small amount of clay into a ball. Next roll the clay out flat. Have the first person press his thumb hard into the clay. Then do the second thumbprint at an angle forming a V with both prints.
With scissors cut around the thumbprints to form a heart. Use your fingers to gently smooth the edges without disrupting the fingerprints. Use a pint and make a hole. Make it as close as you can to the edge being sure to consider the size of your jump ring or key ring.
Place the prepared clay on parchment paper or foil and bake according to the directions on the package. Turn off the heat and let cool completely in the oven before removing. place a small dot of black paint on the charm and quickly rub off. You may want to use a tiny bit of water to remove more paint depending on how dark you prefer it to look. As long as you work quickly you can add more paint or remove more.

Finally open your jump ring spreading the pieces sideways (as opposed to prying open) and thread through the hole. My hole was too far from the edge so I had to spread my jump ring really really far. Then thread your chain through the jump ring and enjoy.
