I could have done with that a few years back, when a customer had seen a feature wall, over the bath. They had seen it in a magazine, the design went like this, coming off the bath with solid dark green 25mm glass mosaics gradually introducing pale green. until midway up the wall pale green was predominant. Then white was slowly added until towards the top it was all white.
They had bought a box of dark green, a box of pale green and a box of white. Guess who had to cut up the sheets to get the desired effect.
I could have done with some help from Gisela that day. The end result was stunning, customer very pleased, and that's what counts. Did my head in though.:lol:
