The method used to create the inlay comes as a standard feature with Vectric V-Carve Pro CAM software. I'll show here how I applied the method to make my inlay, but for an even more detailed step by step description, see this article on the Vectric site.
In the last picture, you can also see another inlay over the first - the name of the guitar "WindSong" - which is inlaid using another method DESCRIBED HERE.
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 Build Your Own Acoustic Guitar - by Jonathan Kinkead, found at my local library.
