The best way is to arrange your wall tile in a pyramid shape.
Position the first tile or sheet of mosaic tiles into place on the wall at the center point of the layout.
Slightly rock the sheet up and down perpendicular to the trowel lines to collapse the ridges and help the tile settle into place.
Be sure to put spacers between each tile as you go.
Then every subsequent row is a process of draping over the pyramid back and forth.
