Pebbles is a 12" x 12" glass mosaic from Sarana Tile. Residentially it works in kitchens, entry foyers and open-plan living areas. The nominal size is 12" x 12", listed metrically as 30.5x30.5cm. Each sheet covers roughly 1 sq ft. Sarana catalogues it in Volume 8 on page 14. It arrives mesh-mounted, so the spacing holds while the sheet is set and it trims down to meet a corner or a niche. Sarana prices it by the sheet.
