Here's a fret jig I made out of plexi. I can position the grain pattern just where I want it or in this case I had a scarf joint to hide, bet ya can't find it. The saw is a Harbor Freight flush cut saw with a stop glued to it so I get the perfect depth on every cut. Holes are drilled for fret markers and I use one of my cut offs to keep the saw 90° to the jig. I love it! easy to use and no moving parts.
