Today I wanted to share the coolest project; DIY Triangle Planters. These planters have a fun 80s vibe to them. Make your own with Makers Mix DIY Concrete, paints from Deco Art and fill with plants or tealights! This project has been featured on the Beacon Adhesives and Signature Crafts Blogs.

Dimensions of Handmade Mold!
Measure a 4 inch triangle shape in the center of a piece of cardboard. At each triangle side measure a 4 by 4 inch box shape. This will form a “Y” type shape. (See Photos)
Fold up all the sides of the box, tape the whole box together using duck tape. (Leaving an opening to pour the concrete)
Grease the inside of the handmade mold using oil and a brush. Set Aside.

(Note: you could also use cooking spray or Vaseline)
Pour 1 cup Makers Mix into a medium sized bowl. (Once used for concrete leave it for concrete or crafting purposes)
Mix 1 cup of Makers Mix with 5 1/2 Tablespoons of water in a medium sized plastic bowl, until well blended. It should be the consistency of brownie batter.
Fill the mold with the concrete a little more then half way.
Tap the mold a few times on the table to loosen any air bubbles.
Next grease the outside and bottom of the dixie cup with more oil.
Press the greased dixie cup into the center of the concrete about halfway. Let set for at least 30 minutes. If you have any extra concrete left over fill the remainder into another mold so you don’t waste it. Let all pieces completely dry for 12 hours, preferably 24 hours before painting.
Once the concrete is dried and set, pop up of the mold.

Note: Concrete will get warm while its drying and setting. Its done when its cold or room temperature to touch.
Start drawing a bunch of rectangle shapes onto one corner of the concrete. Paint the shapes with different acrylic paints.
After you have finished your painted designs, the triangle planters are ready to fill with tealights, small succulents, or cacti. So many possibilities with this project. Create a bunch of these for party tables. Add polka dots to them, gold leafing (pictured above), the choice is yours.

The cost to make these are super cheap. Makers Mix is $7.99, the mold is practically free using a recycled box. Duck Tape is around $1.99 and you can use the paints and vegetable oil you have laying around the house.
Here is a quick video for you to see how easy it is to make these!
