DIY Confetti Geodes (Two Ways)

I don’t know about you, but ever since I was little I’ve been obsessed with geodes. Like, how much more magical can you get than sparkly crystals inside what would otherwise seem to be a boring old rock?

I recently saw some ah-mazing geode cookies on Pinterest, and it got me thinking that #TheConfettiBar confetti would make for some magical geode action.

After testing out a couple of approaches to this, I found two amazing ways to make them: as a wall canvas or as a 3D sculpture. Now while both are super simple to make, they can be a bit time consuming, only because you have to wait for things to dry. I’d say altogether it only takes about an hour, but spread out over a few days if you fully let things dry in between steps.

I’ve got both DIYs for ya below, so let’s get to it!

CONFETTI GEODE WALL CANVAS

You will need:

• Canvas (any size you’d like, but I find I like square sizes best)
• Mod Podge (any kind will do, but the Sparkle Mod Podge would be most magical!)
• Confetti (duh)
• Rigid Wrap Plaster Cloth (cut into small strips) + a bowl of water
• Acrylic Paint / Paintbrushes

Start by pouring a thick-ish glob of Mod Podge onto the middle of your canvas. Using a sponge brush / paintbrush, spread out until you have the size of your desired geode. (I like to go almost all the way to the edge, and if it’s a little lopsided it looks more realistic.)

Pour your confetti onto the Mod Podge, pressing down to make sure as much confetti sticks as possible. Before tapping off the excess confetti, let dry completely — usually at least 24 hours. (Since the confetti glob is thick, if you try to get the excess off while it is still wet it will “run.”)

Once completely dry you can tap off the excess confetti.

One at a time, dip your plaster cloth strips into a bowl of water, using your fingers to wipe off the excess water in a downward motion. You will see this makes the strips extremely pliable, so use them to create an edge around your confetti blob, plus cover the rest of the canvas. (Again, for realism you’ll want it to be less than perfect, getting some creases and folds for texture.) Let dry completely. (Can be done in a couple of hours, but I like to let it sit overnight.)

When the plaster is dry, paint with acrylics. I personally like to add a gold edge, too! Let dry.

CONFETTI GEODE 3D SCULPTURE

You will need:

• Air Dry Clay
• Mod Podge (any kind will do, but the Sparkle Mod Podge would be most magical!)
• Confetti (duh)
• Rigid Wrap Plaster Cloth (cut into small strips) + a bowl of water
• Acrylic Paint / Paintbrushes

Start by using your air dry clay to form concave rock shapes. Let dry. (This part may test your patience a bit, because it really takes 2-3 full days to get hard. It doesn’t have to be rock solid to use, but you do want it to harden for a least a day or two so your Mod Podge will dry in the next step.) The good news is it literally only takes a couple of minutes, and you can make a bunch of these at once / in advance so you always have some on hand!

Once your clay is dry (or mostly dry), use Mod Podge to fill in the middle.

Fill with confetti, pressing to get it to stick, then tap out the excess. Pour a little more Mod Podge on top of the confetti that sticks, and cover with a second layer. Let dry for 12-24 hours.

Similar to using the plaster strips for the canvas, this time you’re going to want to wet them and wrap around your clay. (The wetness might make your clay slippery  — don’t worry. It will dry again!) I covered the outward facing edge, as well as the bottom so it would be a full 3D sculpture.  Let dry completely.

Use acrylics to paint the entirety of the sculpture, adding a gold edge.

If you go smaller with these they make a great paperweight but could you imagine if you made larger ones as a decorative piece?! Pure magic.

While a “realistic” geode looks amazing, who says you have to go classic? Have fun with different color combos, and you can even get a little crazy by sprinkling on some glitter while your paint is still wet! (Would look amazing on either the canvas or the sculpture!)

So there you have it: two ways to make colorful confetti geodes! I’ll be honest and say I can’t choose which I like more…in fact I love the look of both the canvases and the sculptures intermixed on my mantle with some other do-dads.

I have the urge to make about a million more geodes in all different colors — which is your fave??
