I knew I wanted to use two different shades of blue, similar to ones in this photo. I also was dreaming that someone would come in and put up a chair rail in their room. WikiHow even has a tutorial on how to do it. Seems easy enough. But I knew I would need help and my handyman is too tied up with work. So I came up with another option.
Wednesday afternoon I put up tape to separate the walls and create a line for a white stripe.
I painted two large squares on this wall and let my two little assistants go to work. I told them to just paint within the square. It was kind of a mess, but they had fun. You can see some of their work below.
Top and bottom painted, tape peeled off. I let this dry Wednesday night.
Thursday I came back and taped off the area I was going to paint white.
This is my favorite part ... the satisfaction of a straight line. I find it's easiest to take the tape off while everything is still wet. If there are any drips, they're still wet and you can usually wipe them off with a rag.
I used Sherwin Williams Atmospheric on the top and Vast Sky on the bottom.
