Q: what does offset match mean on wallpaper? Susan

A: Offset match wallpaper (also known as drop match) is where the pattern runs diagonally so that only every second strip of wallpaper in hung at the same place, and intermediates strips are dropped by a certain amount. Most paper will tell you how much of a drop you need between each strip to make the pattern match up. Hanging this type of wallpaper when the drop is very large (more than a couple of feet) tends to cause more wastage that other types of wallpaper hanging, so make sure you have enough to finish the room.
