This sound wave design is a more detailed piece that contains two layers of wood used for detail and definition. I can have the word(s) or phrase(s) put on the sound wave, leave it blank, or put it on the back. The sizes of these designs are determined by the word(s) or phrase(s) with a maximum height of 18 inches and a 50 wooden slat maximum. If the word(s) or phrase(s) that you are interested in exceed the maximum amount of slats used, I can customize it to your liking as long as we can discuss details beforehand.
