The inside of a wooden surfboard looks like the skeleton of a fish. And it only gets more beautiful from there. The entire process of making a surfboard from wood (most surfboards are made from foam and fiberglass) is so fun to see. There is so much carving and shaping and clamping and an obscene amount of glue that you wonder why someone would bother to do this. But the hollow wood surfboard ends up being so beautiful and natural that you see that it’s totally worth it.
