How to Make a DIY Skull Mold

This DIY Skull Mold is an easy project for you to add to your list this month! Whether you use skulls for decor in general, or only in October, this project is fun and this mold can be used for anything! The products make it quick and simple. You’ll be amazed at what you can make once this mold is finished. The best part is that it literally took just a few minutes to shape the mold and only half an hour of curing time. Here’s how I did it!

DIY Skull Mold Supplies:

• EasyMold Silicone Putty
• Disposable Gloves (Optional but recommended)
• Parchment paper for work surface
• Item to make mold from, in this case, a Skull Candlestick

EasyMold Silicone Putty is a quick and simple product that you can use to make a mold, even if you just need to replicate one section of the item you are casting. In my case, I wanted to create a skull mold in order to make napkin rings, so I only needed to replicate the front of the skull face and EasyMold Silicone Putty was the perfect product for that. The putty comes in two parts, Part A (white) and Part B (purple). Take equal amounts of each part for your project. You’ll want to keep in mind how large your final mold needs to be, and take at least half that size in each color. Roll them into small balls to determine if they are similar in size.

Mixing the putty:

Combine the two parts by pressing them together and continuing to knead them. The two parts will begin to combine to look marbled. Knead quickly, as it should take you only one minute to get the putty combined. In total, you have three minutes of working time with this product from the start of mixing the putty parts to having your item pressed into the putty.

…until they are one solid purple color throughout. You now have only two minutes to press your item into the putty, so be quick but precise.

Pressing a Mold:

Take your ball and flatten it in whatever shape you will need to cover the object. In my case I just wanted the front of the face, so I flattened it until it was large enough to cover the entire skull face.

Press your item into the putty firmly, evenly and do not pull it back out at all. I actually pressed the putty up around the skull a little more to get a deeper mold. Keep your item there for 25 minutes.

After the 25 minutes are up, you can remove the original item from the putty mold. If you mixed the putty correctly, it should be slightly bendable but solid and should hold the original shape perfectly.

Here is my DIY Skull Mold next to the original item. It always looks a little different, but rest assured, if you followed those instructions it will make a great mold!

Here is the skull mold a little closer up. There you have it, you’re done making a perfect silicone Skull Mold. You can use it for many different materials, like casting resins or chocolate or even make skull ice cubes.

I decided to use some FastCast to make some skull figures for those napkin rings I mentioned above. So here are a few shots of that process, though I won’t go through that step-by-step in the tutorial.

Using the DIY Skull Mold:

I made four skulls with FastCast, painted them with a metallic gunmetal gray, and secured them to some painted wooden rings to make these awesome Halloween Skull Napkin rings!  I have so many more ideas for this mold and can’t wait to try some other designs. I’m thinking of a skull covered picture frame and possibly resin skulls to add to a wreath. What would you use your skull mold for?

Stay tuned for another project coming soon that uses this skull mold in a different way. Can’t wait to show you!
