Shared Girl-Boy Room Accent Wall Idea

My kids have always shared a room and love to at least until my daughter hits tweens and realizes she has a choice. 😉

A shared boy-girl room comes with its challenges for decor. I could pick a neutral color – a gray or beige or green…

But you know me… that was NOT going to happen.

So here we are…. one side of the room for my flowers and all things pink-loving gentle girl and the other for my ferocious naughty dinosaur loving boy.

A quick video to show you more about how I did it!

Supplies Needed for the Colorful Geometric Accent Wall

How to Paint Geometric Shapes on the Wall –

I started by having the kids pick 5 colors each. They both picked very similar orange, green and yellow so that made my job so much easier! There were also a navy blue, light blue and teal that are not shown here.Creating a colorful kids room accent wall

Decide how far in the main colors overlap and the size of diamonds. I decided on 2′ for the overlap and 1′ for the diamonds. The wall is exactly 12′ so using 1′ increments made it simple.

Use a level along with a yardstick to mark the grid.Easy way to create a geometric diamond wall

I marked corners of all the diamonds down and across. See below on exactly how I did it.

Start by taping the first pattern down on both sides. I went down 2′ before I started taping the 1′ diamonds.

Paint the main wall colors – teal and light pink in our case. I used Multi-surface FrogTape® for this because the base paint had been painted almost 2 weeks before.How to start painting a geometric colorful accent wall

Time to start painting the diamonds. Tape alternate diamonds using FrogTape® Delicate Surface  and paint.

 Tip : Make sure to press down the edge of the tape with your nails or a hard edge. This ensures perfect sharp lines. Painting a colorful accent wall using FrogTape

The only thing to really pay attention is to carefully align the edge of the tape to the previously painted line. It isn’t hard at all because you are always following the corners you marked for the diamonds.

Remove the tape as soon as you paint each diamond.

Continue painting alternate diamonds in random colors. I simply went about in my favorite pattern to pick colors – random.

I love that you can use FrogTape® Delicate Surface on paint less than 24 hours old. The paint would take about 30 minutes to dry to touch and I could tape over it.  

I would paint diamonds on one side, go to the other side – tape and paint then come back to the first side and tape and paint more diamonds.How to create a preftect accent wall with geometrical diamonds
