Hello everyone! It’s been a while since I’ve been here at The CSI Project. My name is Rhonda, and my blog is called Mrs. Greene. (You may also know me from Dollar Store Crafts!)
Halloween is my very favorite holiday, so I am excited to share a Halloween craft with you today! I love working with resin, and I’ve been wanting to make my own molds for a while now. How, you ask? I had a brilliant idea!
Have you ever heard of Sugru? I love playing with new and different things, so when I first read about it, I HAD to order some. It’s silicone clay that cures to be durable yet flexible and soft to the touch. I’ve used silicone ice cube trays as resin molds because the cured resin pops right out of anything flexible, so I figured Sugru would be perfect for making a mold! I had some plastic skull rings left over from last Halloween in my stash, so I decided to get experimental and use one to make a little skull mold.
You will need:
- Sugru
- Skull ring (or other item for making impression)
- Wax paper or freezer paper
- Non-stick cooking spray
- Resin
- Glitter
Sugru comes in little foil packets; I used two packets to make my little mold. Since Sugru bonds permanently to almost everything, lay out a piece of wax paper or plastic-coated freezer paper on your work surface to protect it.
Once you cut the packages open, work the clay into a flat sheet that is big enough to stamp with your ring at least once. It should also be thick enough to stamp the image deeply enough that you’ll be able to pour resin into it. Mine is about 1/4 inch thick. Try to make the top surface as smooth as possible so you get a clean impression of the skull.
Spray your ring with just a touch of cooking spray to keep it from sticking to the Sugru. Carefully press the front of the ring into the clay until the entire design is pressed in and you have a complete impression. Lift the ring straight out of the mold.
Let the Sugru cure for 24 hours. You should be able to peel it right off the paper. If it sticks, heat up the paper from the back side with a warm iron until the wax or plastic melts and releases from the silicone.
To cast a glittery skull with the mold, mix up a batch of resin and add some glitter while stirring; carefully pour it in. Be careful not to overflow the mold.
It’s waiting time again! Let the resin cure for 24 hours, then carefully pop it out of the mold. (I had a few little bits of Sugru that stuck in little crevices in my skulls, so I used a stiff-bristled toothbrush to clean them up.)
Use sharp scissors or a craft knife to trim any excess resin around the edges.
Now you can use them to decorate all kinds of things! I think they look cute as barrettes. Since the silicone is also heat proof, you can use it with polymer clay as well.
