Thank you for all of the compliments on the Chevron wall! We love it and thought we should document the process in case any of you dare to tackle the measuring...
We first painted the walls white because they were tan to begin with and we wanted a gray and white combination.
We then measured the total length of the wall and divided by how many angles or "chevrons" we wanted. Our wall is about 13.5 feet long, so we converted that to inches (161) and then divided by the amount of chevrons we wanted (10). This makes each half of a chevron 16.1 inches in length.
To make sure they were straight and level, we measured all of them where the ceiling meets the wall and then measured down from each one the thickness of each chevron stripe (ours are 12" wide).
We used a level to make sure each dot was in line with the one to the left of it and from above. Doing the wall one "column" at a time made sure all measurements stayed as precise as possible.
On a side note, make sure you tape from point to point in a straight line and then cut the tape at all angles with an Exacto blade to create sharp corners.
If you forgot to cut one, it will look like this:

Disclaimer for crappy pictures: I just realized the reason these pictures are so unclear is because I forgot to change my camera's resolution back to normal after taking low-res pics for items to sell on Craigslist. Sorry!
There you have it!
