#45: I really like the I mark surrounded by the acoustic holes. Nice font too. It'd be good to see different variations on the fonting for the imprint and the I, maybe with a few different color fonts on the #45. Again, really nice design with this one. Thanks,
In #45 I wanted to create a dual element design. So I used the negative space as the surface of 2 pieces of acoustic wood and the letter "I" is formed in the dark space between them.
