Sometimes the best DIY’s come from the scraps of other projects. After making a few of these plaster planters , I was left with thin colored plaster flakes that came off the molds. And I thought, these would make the perfect terrazzo look. So after a little experimenting, I created this DIY confetti terrazzo desk organizer using colored plaster flakes and white plaster mix. And this isn’t one of those faux painted terrazzo pieces, this is the real deal with colored flakes mixed in.

See? I love all those colorful confetti pieces in there! And it is perfect for organizing all your desk accessories or can even be used to corral jewelry too!

Materials for DIY Confetti Terrazzo Desk Organizer:

–Plaster of Paris
–Acrylic paint
–Square silicone mold
-Small dishes or containers to make the organizer indentions
-Mixing bowl and spoon
-Vegetable oil
-Wax paper

Begin by mixing up a small amount of plaster (about 2 spoonfuls) with water until it resembles cake batter. About 1/2-1 spoonful of water should be good. Then add a squirt of acrylic paint to the mixture and stir to color the plaster. This will start to seize the plaster mixture, so you can add a bit more water if needed. Once mixed, use the spoon to smear the colored plaster onto a sheet of wax paper.

Let the plaster dry and repeat with all the other colors you want in your organizer. Once the plaster has dried (about 30 minuts), break up the plaster into small pieces.

Next, mix up 2 cups of plaster with water until it resembles cake batter and add it to your silicone mold. Sprinkle on all the small plaster confetti bits.

Rub the outside of your small bowls or tins with vegetable oil and press into the plaster to make your compartments.

Let your plaster cure fully (about 1-2 hours). Then use a pair of pliers to remove the bowls or containers from the plaster. And then remove the tray from the silicone mold.

As a last step, sanded the top of the organizer tray gently to smooth it out, and then painted the edge of the desk organzier for a little extra color.

I made several DIY confetti terrazzo desk organizers, each with different compartments. Like the one above where I pressed a pencil into the plaster when it was half cured to create a few pencil holders. Then I used one of the tray bowl molds in the finished product too. The possibilities are endless! I can’t wait to try this technique for molding a planter next! Isn’t the colorful confetti terrrazzo just so fun?!
