Double PU2907-5 is a wallpaper designed by Patricia Urquiola for Tres Tintas, in blue and grey. Fine lines and small half-circles linked into a dense diagonal mesh, too small to read as separate shapes from a distance.

The colour of the lines sets the tone of the whole wall, so from across a room each colourway reads as a fine, close-woven surface. Made in Barcelona and printed to order.
