With wall paint and wall covering, you can make a mistake and not completely destroy your budget—you can do a little trial and error and find what works for you. You do that with plumbing, foundation, a load-bearing wall, or anything with electricity? People literally can get hurt. With paint, the worse thing that’s ever happened to me is I got some splattered on my face because my wife didn’t think the joke that I made about her jeans was funny. You can live with that.
