Step 1:  Create the clay form

cutting clay model

Flatten some polymer clay into a circle that is about 1 1/2 inches in diameter and 1/4 to 3/8 inch thick. The clay can be any color because it will only be used to create a mold for the resin.

Lightly draw the shape of a heart using the tip of an Exacto knife, then cut it out, trimming the excess from the edges. Keep in mind it doesn’t have to be perfect.

Using your thumb or any finger for that matter, press firmly into the center of the heart to create an impression of your fingerprint. Then, bake the heart according to the directions on the polymer clay packaging.

Step 2:  Create the resin mold

Once the heart is baked, you can use the Exacto knife to carve around the edges of the heart to give it character. If you want the edges smooth, you could skip the carving and lightly sand the edges to a smooth finish. When you are satisfied with the texture of your heart, dust it off with a clean cloth and take out equal portions (about 5/8 – 3/4 inch in diameter) of the white and yellow Amazing Mold Putty.

Knead the putty together until it is a uniform light yellow color. Once the putty is a uniform color, flatten it a bit against your work surface, then gently press the heart into the putty, being careful not to push through to the other side of the putty.

When the heart is positioned, let it sit about ten to fifteen minutes to cure in rubber, then gently peel the mold away from the heart.

After filling the cavity with the resin, let it sit to cure, away from areas where dust or particles might settle into it. When the resin is cured, pull it out of the mold.

  1. THANK YOU! I have wondered how to do a thumbprint type craft for so long, and this is amazing and perfect!

  2. Katherine, I’m wondering if you could use something like silly putty for the MOLD in a pinch? Have you ever tried such?

  3. @Carla, I haven’t tried silly putty but I would be worried that the resin would stick to it and not come out.
