What's the difference? 

When deciding between a Mural and a wallpaper concider the differences before you choose. A Mural doesn't have a pattern repeat. It's a single image printed on wallpaper in a specified order. Application is a one chance process leaving no room for mistakes hence getting the professionals in. Here's one I've done recently (see image above.) A wallpaper on the other hand will have a repeated pattern. This sometimes will show as a straight repeated pattern or a diagonal one if it has a drop pattern (see image below.)
