Just a quick question about my fiddlerman CF bow in the case from the artist violin outfit.
I am starting to notice that my bow has a strange spot on the hairs where it comes close to the spin holder.
It was not originally there and I’m not sure what is causing this. It could be the humidity or temperature since the spot is kind of sticky. However, it is cold and dry where I live right now.
My best guess is that you may have touched that area with your fingers without realizing it. The oils from our fingers will make the hair look dirty, and make it hard for the rosin to stick to that spot.
