Listellos and inserts can be manufactured by the tile supplier and match the tile or they can be selected from a variety of custom designs to enhance the wall or back splash. Deco’s and listellos can add a subtle highlight to the wall or they can become the dominate design feature. We know listellos and decos can be pricey so we try to design in the most price conscious way possible. For example, a lot of mosaics can act as an insert or listello because they come on a 12x12 mesh mounted sheet that can be cut to size so depending on the area we can add a nice touch in an inexpensive way.
