When you seek you beautify your home through the use of appealing crazy wallpaper designs, let not your sense of naivete dictate the choices you make. There are many designs out there, far more than any one person is likely to be able to view and process, and you might lose sense of what would look good in reality when confronted with such a smorgasbord. Modern crazy wallpaper designs may be contemporary, but remember that 'modern' changes as the years go by and become 'antiquated'. You want to get something that will outlive the current design trends of the day, unless you can afford the waste that changing wallpapers entails. Even if you can afford it, the environment cannot, so choose wisely and for longevity.
