Fiberglass mesh sheet 1m x 3m.
Creating a mosaic pattern on a wall can be very difficult if you try glue each individual tile because the tiles can slide down as the glue cures. There is an easier way. The solution is to create the design beforehand on a sheet of fiberglass mesh, and then glue the entire sheet of tile up. This allows the artist to work at a table and create detailed designs that would otherwise be all but impossible.
