Painted Geometric Wall

I'm still working on the small bathroom my kids use. Updating it without spending much money.

I already updated the vanity, you can check it right HERE, and I covered that plain tub with a wood panel to make it look way better, check that HERE.

Lately, I've seen tons of beautiful designs on walls, so I thought the wall behind the door would benefit from one of those designs.  This is the one I chose, fun and simple:

This is the space or wall where I wanted to paint my design:

Since I was not going to buy the stencil I set to create my template.

1. Using a poster board I began drawing on the back of its circles.   I used a plate and drew the first circle on a corner of the poster board (fig. 1 ), then I continued drawing and connecting circles (fig. 2).

2.  Another circle was drawn in the middle of them ( fig. 3), creating the basic design.

3.  Using a square ruler I drew straight lines throughout the middle of the circles (fig. 4), doing it both ways (fig. 5), which helped me to continue drawing perfectly aligned circles.

4.  I cut the poster board to discard pieces that didn't have perfectly full or half circles (fig.6,7).

5.  Now it was time to cut with the utility knife.  I cut the figure inside each circle, making sure not to go all the way to the corners (fig. 8).  Do not discard the cutout pieces yet, later on, you are going to need some of them.

6.  I did not cut throughout the pattern at both ends to keep the stencil sturdier (fig. 9).  The diameter of each circle was 8-inches (fig. 10).

7.  With the stencil ready it was time to draw the pattern onto the wall.  I began at the top left corner (fig. 11), continuing right and down, making sure it was level.  I used a pencil but it's better to use a color pen that matches the color of paint you're going to use to paint the design.

8.  With the cutout pieces it was easier to trace around those hard-to-reach places and corners (fig. 13).

9.  I was unsure of what color to use, I painted my three options and settle on the left one, metallic grey on grey. Fig. 14.  ( Even though I did paint my choices on the wall, it's not a good idea! I had a hard time covering the ones that were not chosen!)

10. I used FolkArt craft paint Metallic Gunmetal Gray, it worked better for me using a flat angled artist's paintbrush (Fig. 15).

11. I put painter's tape all around the area to be painted.

Then I had to paint, and paint, and paint!!!  

Believe me, I am a very patient person while doing something like this, but by the time I was in the middle of it, I was not happy :/

Total painting time: 10 long hours!!! Thank goodness it was a small wall!  In the beginning, I was thinking of applying two coats but after my third hour of painting, I knew that was it!! I was not going to do a second coat. period!  You can see my "when am I going to finish?" face (fig.16)!  and that was the beginning!

Well, I like how it turned out, but I wonder if it was all worth it!
Spending $40 plus S&H or spending 10 hours of painting with a very sore wrist?!  What do you think?

I need to spruce it up a little bit, that's going to be until next time!
