DIY Geode Skull Craft

There are certain craft supplies that I tend to buy waaaay too many of each season.

For Christmas, it’s clear ornament balls for us to customize. For Spring, I buy way too many grapevine wreaths. And for Halloween, my most hoarded craft supply has to be these hallow, plastic skulls.

Just this year alone we have used them in four different crafts:

My daughter loves all things Halloween and is going through a real geode kick, so this was a fun and easy craft for us to make together – and I think it turned out pretty cool!

We already had all of the paint and tools we needed so this craft only cost us $3 to make with craft supplies from DollarTree. That crystal rock effect is actually created by using crushed vase filler. Glass or plastic both work great, but if you can’t find any, you can use aquarium rocks instead.

If you want your geode skull to last for years, I suggest first painting it with a chalk paint as a primer before painting with the acrylic paints. Once all of the paint is dry, seal everything with a spray sealant or mod podge. (If this is going to be a one-time use decoration, you can get away with just using the acrylic paint on it’s own.)

Please note that we painted our skull after filling with vase filler but I’ve changed the instructions to encourage you to paint first, fill second. I think it’s just a bit easier, plus it only requires you to use the vase filler once (which is a bit messy).

I think this geode skull looks awesome as a stand-alone piece of Halloween decor, but you can step it up a notch by adding to a wreath or cutting through the top of the skull to insert some fake flowers.

Tip: if your acrylic paint doesn’t easily stick to the plastic skull, try painting the skull with chalk paint first.

How to Make a Geode Skull

Using an Xacto knife or scissors, cut a large hole in your plastic skull encompassing one of the skull’s eyes and most of the same side’s cheekbone. Discard.

Use hot glue to secure floral foam inside of the skull, sealing the hole but ensuring there is a bit of a cavity/dip still where you cut the skull.

(If you’re having a hard time positioning the floral foam, you can stuff some cotton batting into the skull before securing the foam to help with the structure.)

Paint the skull all over with a charcoal gray paint. (If you want the paint to last for more than just one season, you may want to paint the skull first with chalk paint. Allow the chalk paint to cure before painting with the dark gray paint.) Allow gray paint to dry.

Place a tray down to catch your vase filler and place the plastic skull overtop.

Apply hot glue to a large section of the floral foam, then sprinkle the vase filler over the hot glue. Allow to set for 2-3 minutes, then shake off the excess vase filler over the tray.

Repeat this process until the entirety of the floral foam is covered with the vase filler.

Use hot glue to trace around the edge of the skull’s hole and sprinkle with vase filler. You may want to also add a few “random” pieces across the face of the skull. Allow to dry.

Paint a thin gold outline around the edge of the cut-out area and allow to dry.

If desired, spray the painted areas of your geode skull with sealant.
