They are so easy and inexpensive to make. It took me a couple days to complete because of drying time, but the actual work is quick.
I used a 1x6 from Home Depot, sanded all the edges and corners and then stained it. I let it dry overnight and then lightly sanded it again so it was nice and smooth.
I marked every six inches and then taped my squares so I could apply paint. I used Annie Sloan Chalk Paint because it dries quickly and distress easily.
After the painted squares were dry, I used a plastic stencil from Michaels to paint the numbers. I did get a lot of bleeding from the paint under the stencil, but once everything was distressed, it was not noticeable.
I did two coats of white paint and only one coat of the blue paint before distressing. I definitely like it better with two coats of paint. The blue looked too washed out, not really distressed.
I love the way these turned out. I can't wait until I can actually starting marking both my girls' heights!
