· The best way to rotate a piece of glass is to do so on the board away from the mosaic. You can sometimes mistakenly place a piece of glass while you’re rotating it, intending to fit it in somewhere else.
· Larger pieces are more difficult to place as the mosaic fills in. Place larger pieces first so you don’t have to trash them later and lose points.
· Before you trash a piece, pick it up and move it over the mosaic to ensure there’s no place that it will fit that you might have overlooked.
