Layering means adding more than one emitter/magnifier so that the effects are greater than they would be if used individually. The below photo shows a large 45-degree corner emitter (approximately 9 inches wide and 33 inches tall) made from 1x10 lumber using a circular saw with cuts made at 45-degrees.

The 45-degree emitter by itself will emit large amounts of good energies into the room. Adding the two 16-emitter crystal circles not only amplifies the 45-degree emitter, but also these crystal emitters will emit of lot of good energies by themselves. Further additions to this layering might be L-emitters, 16-in-a-row or 7-in-a-row amplifiers, and/or more crystals anywhere on the wood face.
