Paint Your Wall With a Chevron / Herringbone Pattern

This wall pattern requires a bit of preparation but is fairly easy to execute.

I just did this in my office as I wanted to create something fun and soothing (to me).

The first step is to paint your whole wall with your main color of choice.
In my case I chose Sherwin Williams Waterloo (SW 9141)
This step is actually fairly easy, paint one or two coats depending of your needs.

The only difficulty is ensure you cut clean lines with your other walls, ceiling, and trim. You can put tape all around your wall to help. Just know that if you are using blue tape, you have 2 weeks to complete the project (that's the maximum recommended time to leave the tape on so you can remove it easily and without residue).

You can tape however you want for your own custom design but I will focus on the chevron / herringbone pattern here.

This is the most complex step as you will want to make sure you line up your design properly with your wall edges.

As a reference, I used 18" wide and 8" tall chevron to start with.
My tape is 0.75" wide.

Tape vertically center on the wall (the middle of the tape should line up with the middle of the wall).Measure the first half of the wall (left or right) and divide the length by the width of the chevron +the width of the tape. If you end with a round number, awesome, you can proceed. I personally wanted a full chevron to end at the the edge of the wall so I made some adjustments to their lengths. Extended or shorten your chevron a little bit to find the right measurement.

First, find you middle line vertical line.

Divide the height of your wall (don't count the trim!) by 8" (the height of the chevron).

Just like in the previous step, you might want to adjust the height of you chevron so that you have an even number of sections. Mark those sections on the tape as well as on every other tape to the left and to the right.

On the unmarked vertical tapes, mark similar sections shifting them by 2" or 3".

You can use a laser level to quickly and easily repeat the marking across vertical tapes.

Finally, you will need to join the vertical lines with tape following the diagonals you just marked.

The key here is to be very careful on your taping.

Start from the center vertical, in the middle. Put your tape on the marking you created and go in diagonal to the next vertical tape on the right 2" - 3" lower, along the marking. Don't skip the marking or you will have a very odd looking chevron. Repeat on the next vertical tape on the right, going up this time.

Repeat left and right until you have a full line.

Repeat the process to add your diagonals above and below the one you just created.

You will want to make sure that you alternate the taping of the diagonals in such a way that the tape is once inside the 8"marking, once outside the 8" marking. This will ensure that your chevron are the same height as your background lines.

Check the picture for better understanding.

Before painting the chevron in their color, I suggest you paint the main wall color on the tape. This will seal the tape to the wall and avoid the bleeding of the lighter color.

Only paint on the tape on the side of the big chevrons. The small ones will stay in the main color (and once the tape is removed, they will all be the same size). A good tip is to put a small piece of tape on the small chevrons you shouldn't paint.

Now, paint your chevron in the color of your choice.

I chose the Sherwin Williams Blustery Sky (SW 9140). If you look at the color palette, it is a shade light than my main color. I think this yield the best result but you can experiment!

Remove the tape and enjoy your new décor!
