Susan Jablon Mosaics Hi arbo, the grout is TEC AccuColor Standard White Sanded Grout, http://www.susanjablon.com/tec-accucolor-standard-white-sanded-grout-9-75lb.html. And this is a curved subway tile, so it actually has a curved surface sticking out from the wall unlike a traditional subway - probably why it looks like ovals! When you have your tile installed we'd love to see photos! Milk glass is beautiful!
bellbeck Was the wall behind the tile painted in the grey owl first or is it just placed on basic white? If I'm not mistaken the grout looks gray? Susan does the Tec AccuColor Standard White take on a gray look?
