Here’s a guitar by inlay specialist Larry Robinson which is inspired heavily by the Lindisfarne Gospels, from my part of the world. (Must take a trip to Lindisfarne again when the weather improves) The inlay is all done by hand, not machine! I like some inlays I’ve seen on guitars, others are a little over the top, but I’d love to see the guitar in person, though I don’t think there’s any plans to bring it to the home of the Gospels.
Larry has written a book on inlay too and there are lots more examples at his site. Lovely stuff!
