Our playroom makeover has been a challenging one for me to get started with, but once I narrowed down my design all the pieces just fell into place – including this DIY Boho Wooden Round Wall Decor piece.

From the start I wanted some type of accent wall. One that wasn’t too juvenile and could grow with my children and this space.

The inspiration for this wall? This area rug!

How to Design Your DIY Geometric Wall

Step 1 – The first step I took to designing this wall was to map out my triangles and colors. I used the free version of Canva online to create this plan. Putting this rough draft on paper helped me to visualize where I would need to tape.

Once your plan is in place, grab your level and painter’s tape. I prefer the green Frog Tape!

Step 2 – You can start at the top or bottom, but I started at the very top navy triangle since it was my largest. Use the level to create a straight line for the base of the triangle. Measure halfway across to find your center and placement for the top point. (If your base line is 12″, mark a point 6″ in and 12″ up for the top of your triangle.) Then use a ruler or straight edge to connect your points.

Tip: make your points with very light pencil marks before taping. You can clean off any pencil marks with Magic Eraser once the paint is dry.

If you have textured walls like I do, press your painters tape firmly into the wall with your finger to ensure the tape is adhering into the grooves. You will then paint over your tape with the original wall color to create clean lines. Check out the full tutorial for painting crisp lines.

For triangles that are touching without any painter’s tape gaps, you can either free-hand or wait 24 hours and apply the yellow Frog Tape to paint your next color.

Step 3 – Start painting! Follow your plan and paint each individual color. You may need to do two coats of each. Wait 1-2 hours between coats and once the final coat is done, immediately remove your painter’s tape.

The Exception: I found with the Valspar Integrity paint that removing the tape before it was completely dry caused stretching and paint removal. If you find that your paint is coming up with the tape, STOP. Wait until fully dry to pull your tape. If it’s STILL coming off, score it with a blade before pulling off your tape.

I just love the way this turned out!! It is so fun and brings color to our playroom space! Stay tuned for the full reveal!
