I wanted to add some texture to a wall in my kitchen that was not in the best of shape. I bought textured wallpaper from Amazon and cut it into pieces 2.75 by 7.75 inches.
I then dipped each "brick" into a pan of water and stuck it to the wall, making sure that it was level and evenly spaced. Mine are spaced just a little over 1/4 inch. Once painted, minor imperfections will not even be noticeable.
It is pretty hard to get a good picture of the faux brick. The important thing to me is that I no longer notice the wall's imperfections.
I found the tutorial for this on Pinterest. Where else? I think it was genius!
