Things You'll Need
Instructions
Select the portion of your layout that you wish to expand. You may wish to make the track look like it continues on into the distance, or you may want to create the effect of a denser forest.
Position the mirror carefully to create the desired effect. You may need to experiment with the angle. Viewers of the layout should not be able to see themselves in the mirror nor should the mirror be placed at an angle that will distort the background, making it look unrealistic.
Hide the edges of the mirror. This can be done by placing trees, rocks, or other scenery over the edges of the mirror. Bridges and other structures can also effectively hide the edges of the mirror.
