My next sound wave design is the largest design I have created and consists of more layers of wood for more 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 30 inches and an 80 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.
