Hi Stephanie. This is a Show House room so a decorative painter did the wall treatement for me. She started with Benjamin Moore # 198 Cornsilk for the base treatment. Benjamin Moore has a great group of opaque pearl treatments that go over paint color which did the effect you see with the stripe and diagonal walls that seem to glow. The painter use B. Moore opaque Pearl paint (not sure which but they are opague and the paint store can help make a selection. We used it as a strie treatment over the base color. Then the pearl paint again to create the stripes and diagonal pattern over the paint treatment. She did the stripes and diagonal wall freehand by marking the walls lightly with pencil to follow the lines. Good luck, it is a lot of work but oh so gorgeous.
Regards,
Karla
