Why do British papers cost so much more to hang?
British pulp papers like Sanderson, Osborne & Little, Cole & Son, require the extra step of blankstock lining. What this means is that the room must first be wallpapered with a plain manila colored paper. The paper must then dry, usually overnight, so even a small room that normally takes one day becomes a two-day job. Also there is an additional material expense of the blankstock paper usually supplied by the professional paper. More on the use of blankstock lining.
