Unsightly wallpaper seams can be avoided by following the proper procedures for “booking” and smoothing wallpaper. “Booking” helps wallpaper to evenly absorb the moisture that activates the adhesive so you don’t have to worry about wallpaper shrinking up while it sets. A wallpaper smoothing tool should be used after you hang each strip. This will help the seams line up and smooth out the paper. A seam roller can also help seal and set wallpaper seams. It is important to know if you choose a grasscloth or natural fibre wallpaper, that seams will show because the natural fibres do not create perfect seams. This is actually a style choice and one reason why coverings like grasscloth are popular with decorators who are looking to create a natural and textured look in their space.
