I thought I'd start off with a little project that was easy, inexpensive and provided (almost) instant gratification. I'm always looking for ways to change things up in our house and painting is one of my favorite ways to do so.
This is my living room wall before the project.
The walls in my house are wonky and nothing is level so I eyeball everything, but if a level works for you, use it. The first step was to find the center of my wall, which you can do by measuring or by finding a focal point. I used the middle hook on my shelf as my starting point. Getting this line perfect is important because all of your other lines will be drawn from the first line. I measured from the end of my wall (the far left) to the middle hook and marked the spot with a pencil. It was 96". Then I measured 96" starting from the top left corner of the wall and worked my way down. I marked about 5 or 6 points and then connected the dots (vertically) with a yard stick.
Once the first vertical line is drawn, you can measure out from there. I started from my first line (the line on the middle hook) and measured 19" to the right. I did that at the top, at the bottom and a few spots in the middle. Once I had a few points marked, I connected the dots. Then I had two vertical lines side by side. I continued from there until I reached the end of the wall to my right. Then I moved to the left, marking 19" until I had vertical lines that reached across the entire wall.
Then I taped along my pencil lines starting at the top and working my way to the bottom.
I used frog tape and was pleased with the results. I have plaster walls which are anything but smooth, but I pressed the tape down really well, and considering the texture of my walls, there was very little bleeding.
If you tape to the right of your pencil line, tape to the right of every pencil line.
Next step is to mark every 14" down each strip of verticle tape.
Make sure to mark in the middle of tape.
