There are various paints you can use for your stencil wall art. If you are doing it in an adult bedroom, you can use flat paint as it is easier to clean than other high-traffic areas such as the living room, family room, or bathroom. If you are doing your patterned wall in a bathroom or any high-traffic areas in your home, it is best to use another paint sheen such as eggshell, gloss, or semi-gloss. You can also mix paint sheens, just like what I did in this blog tutorial of patterned walls with different sheens.
