Becky told me that my violin arch looked like a cat sticking its butt up to arch its back to avoid your hand.
So here’s where I’m at with violin no. 1:
The back of a violin is usually a nice smooth arch, and the spruce top should be taller with a larger flatter section. Apparently a longer stretch of straight grains is better for resonance. But as you shape the arch, for a long time it kind of feels like the cat in the third panel above.
See the difference?
