It's a hot topic right now in the design world. Why would you use a decorative painter, when I can use wallpaper? The answer is really simple... you can't achieve the layers, effects, colors and custom design with wallpaper like you can't with paint.
Right now the trend with wallpaper is bringing back the mixed patterns and colors of the 70s. This trend has made the decorative painters shift their portfolio to add unique textures and patterns that can't be found with wallpapers.
