Designer Rick Rivadeneyra and ceramicist Suzanne Sollenne are California natives who sell their tiles and other work through the Coastal Artists ebay store. Their relief and other types of tiles are unmistakably Arts & Crafts, from subject material to glaze. They currently have several dozen different designs available, from relief tiles in striking wooden frames to borders and multi-tile friezes. The stock changes almost every day, so keep an eye on their site!
