A: Hello Ck and thank you for your question. You can provide a finished look for your exposed edge using a Schluter edge trim piece (http://www.homedepot.com/s/schluter%2520edge%2520trim?NCNI-5). If you are using the Parkwood Beige with Cherry Dot Ceramic Pinwheel Mosaic (Internet # 205347475), consider using an antique bronze finish such as the Quadec (Internet # 202608670). Since different sizes are available, make sure the trim piece used will accommodate the width of tile installed. Best wishes on your project.
