... it's the back. nobody's gonna see it
I tried two different methods for marking the frets. One is a wood filler and the other is wood. You can see in this photo that the filler is an off-white, and the wood looks awesome.
nothing like the real thing.
So here's the jatoba (fretboard) against the mahogany body. Notice the jatoba's a couple shades darker. Looks nice, eh?
You'll notice the piece of white wood in the fretboard... those are the "frets". turns out that the wood I got is way thicker than I desired, so I take a dremel and shave every piece down by hand. The fretboard took 3 hours to mark.
