Chalk paint is popular for good reason. It's easy to work with and easy to sand which makes getting the distressed look super easy!
Apply Vaseline any where you don't want paint to adhere. After you paint the piece and it dries, simply wipe those areas with a paper towel to remove the paint!
Apply dark wax over your paint for an aged look. Focus on the corners and areas that would normally get the most wear and tear.
You can force paint chipping to begin by using a paint scraper to remove paint in some areas.
