Just did a Dining Room ceiling with the stuff. http://www.anaglypta.co.uk/our-papers/style/heritage/item/derby?category_id=12. 12 x 16 ceiling dimensions.. Looks nice when painted, but what a PITA to hang on a ceiling. 3.5 inch repeat small squares and circles in the pattern. I put it up the 16 foot direction simply because there would be less waste that way. Lots of light coming the 2 large windows made everything more prominent looking. Had to follow the directions for soaking time (10-12 minutes for full stretch) and brush very carefully to avoid over flattening the raised pattern. No seam roller either. Just a light tap on each seam with the butt of the bristles on the smoothing brush. I should have taken pics of it, but forgot. Very satisfying results but a difficult process to get there.
