Spoonflower – Overlapping Seams


Re my previous post … this manufacturer, Spoonflower, specs that the seams on its wallpaper should be overlapped – by as much as 3/4″.

On a busy pattern, you might not notice this. But when there is lot of blank space (white area), and when light is coming at an angle (see photo), you’re might notice it.

If you hunt, at every seam, you can spot a ridge the height of the wall, that’s about 3/4″ wide. To me, it’s not much of a big deal. Once yo uget used to it, you don’t even notice. In fact, I have authentic 1930’s and 1940’s wallpaper in two rooms of my home – with overlapped seams – and it doesn’t bother me in the least.

Truthfully, overlapping seams actually has many advantages. For one thing, when wallpaper gets wet with paste, it absorbs moisture and expands a little. Then when it dries, it can shrink a little. This is how you end up with tiny gaps at seams.

Second, overlapping the seams can reduce stress on the wall surface, and prevent the layers within from delaminiating, which can cause popped seams. (Do a Search here on “delaminate” for more info and pictures.
