How To Build A Mosaic
Mosaics can be built in multiple ways for almost any kind of surface.
The most decorative style is "positively set", which means that the irregularities of the tessera are showcased. "Negatively set" produces a smooth surface and is best for floors.
Mosaics can be built on fiberglass mesh and installed with thinset. They can also be built on foam or wood backing boards for wall mounting, adding a nice additional depth to the artwork.
