The first step in designing and building a harp is... designing it. This time I'm using the computer. Oh how I love those bezier curves. It's a snap to tweak it here and there until it looks just right. I also like being able to accurately space the strings, then with a click and a drag adjust their angle with the sound box until I like the shape of the harmonic curve along the top. Back when I did this by hand I had to re-draw everything if I wanted to try a different angle.
