Polymer Clay Molds

Make your own Polymer clay molds using polymer clay. It's easy! Look outside for items in nature.

This was a fun trip out into the Arizona desert, to come up with some unique looking textures. Suitable even for younger ages but be careful of the creatures that may be lurking! Not near the desert? Any outdoor adventure can provide suitable materials.


Age: 10 and up

Difficulty: Easy

Time scale: 1 out of 5 (not including baking time)


  • Water
  • polymer clay (Sculpey, Fimo or Kato. Any brand will do.)
  • Gloves
  • Something from nature for texture like a dried cactus or a rough rock.
  • Toaster oven
  • oven thermometer

Make Polymer Clay Molds

Condition a fairly large piece of sculpey® until it has softened.

Roll into a ball and then flatten so it is about 1/4 inch thick. If you want to have a deeper texture, the clay will need to be thicker.

I used a dead piece from a cactus. There are really interesting shaped holes that the clay can be pushed into. Remember, the thicker the piece of clay, the more you can push it into the holes, so the deeper the texture will be.


Be VERY careful if you are in the desert and plan on using a dried cactus. There are dangerous, poisonous creatures that may be hiding. Snakes, spiders, scorpions, may all call these home. Check before picking the cactus up and wear gloves! Kids will need adult supervision for this part.


Pour water on the dead cactus before squishing the sculpey on. This will act as a release agent to keep it from sticking.

Now, push the flattened piece of sculpey onto the dead cactus. I wouldn't advise using a live cactus. The prickles will poke right through those gloves!

Lift one edge and peel back slowly. Be careful not to stretch or rip the piece. If it is sticking a bit, this actually can make the texture even more interesting. Just make sure you can get it off, without ripping it.


There you have it. This has bumps in various shapes and sizes, with some deeper than others. I like it, just like this.  If you aren't happy with the results, just roll it up, squish it down and try again.


Search around for more interesting textures to make more polymer clay molds. This rock looks good.

Add some water.

Flatten another piece of sculpey and push it onto the rock. Make sure it doesn't slide around.

Peel off carefully and check to see if you like it.


When you have had as much fun as you can possibly stand, it's time to head home and bake your pieces. Use a toaster oven and bake according to the instructions on the package. Oh, and one little piece of advice.... use an oven thermometer and don't leave this unattended while cooking. If you want to see what happens, if you don't do this you can check out my craft wrecks!

Using sculpey or fimo to make polymer clay molds, is easy and inexpensive. These can now be used to add texture to your polymer clay projects.

Inside and out, there are many items that can be used to make polymer clay molds, with a variety of textures. If you are on the hunt for some interesting designs or textures, PLEASE make sure that you aren't using  live plants, archaeological specimens or in environmentally sensitive areas. Polymer clays have oils in them that may damage the surfaces they are applied to. Be aware and responsible on your quest.
