Oooooo. Think long and hard about wallpaper. People generally curse their decision when they go to remove it. Yes, they make special products to remove it and yes, there are techniques and yes, it can be painted over. I realize all that. But generally speaking, it's not without headache. It fell so out of favor that some stores like Home Depot stopped carrying it altogether. If you have small children, I don't recommend it. Speaking as a former kid who would stick her fingers under the seams and tear it, let's just say paint is safer. Also if a kid draws on the wall, at least you can do touch-ups with paint. If you're going to do it, maybe just the top half of a wall above molding. Good luck!
