In addition to showing how I made my particular headstock, I will be demonstrating the broader technique of liquid inlay. As opposed to traditional wood inlay - which involves fitting many carefully cut parts into carefully cut pockets - liquid inlay uses a liquid binder, such as epoxy, mixed with colored filler to make inlays with nearly unlimited colors and materials.
Disclaimer:Before I get started, I want to say that I am NOT an expert luthier (stringed instrument maker). I tried my best to do my own research and follow the plans for my guitar design, but only time will tell if I was successful.
If you choose to make your own guitar, please do your own research using professional guides. There are several amateur luthier communities online, as well as good books. I personally used How to Build Your Own Acoustic Guitar - by Jonathan Kinkead, found at my local library.
