I came across this idea of Geo Wall art made out of foam from this blog here & since I had some extra foam boards from when I made my tank backgrounds I figured why not try this out.. & I am SO GLAD that I did because these turned out super cute!!

What You'll Need :

Styrofoam - any kind will do. I used the sheets that you can find at Lowes

Printable triangle guide - you can find it here

Sharp knife or something to cut the foam with


Smooth Finish Foam Coating

Spatula or Popsicle Sticks - Something to spread the coating

Acrylic Paint

Paint Brushes

Painters Tape

Duct Tape (optional)



Step 1: Step 1: Cut Out Your Pieces

Print out a few copies of the triangle printable here

Cut out & trace the guide onto your foam pieces.

Then use a knife or foam cutter, cut out the Styrofoam pieces along the lines you just traced.

Step 2: Step 2: Make It Smooth

Now you'll want to take the spatula/ popsicle stick or whatever you have to apply the foam coating to the foam & do just that, lol apply the coating to the foam.

I ended up applying 3 layers total, letting each layer dry before applying another.

Then take a piece of sandpaper & sand down any sharp or jagged edges.

Pictured : on the left is one without anything on it & on the right its what it looks like finished with the coating on & sanded down.

Step 3: Step 3: Figure It Out

Figure out & place your pieces in the order you'd like to hang them on the wall.

Then if you are planning on having some or all of them be 2 different colors, go ahead & place your painters tape onto those pieces.

TIP: to help with any kind of bleed through I painted some white acrylic paint over the edge of painters tape

Step 4: Step 4: Paint!

Take your acrylic paint & get to paintin' 😁

Step 5: Step 5: Hang Them Up

Now it's time to hang your artwork up. I put a piece of duct tape on the back in the middle to make it more "secure" not sure if it actually will but it sounds good lol.

Then I took an exacto knife & cut a small hole into it where the tape is. Make sure you don't cut too deep & go through the front!

I used some small nails that I had in the garage to hang them up since the pieces aren't heavy or very big, the smaller nails worked perfectly!

& there you go, you're all done 😊 Congratulations!
