I fletched my first arrow last night. The shaft is made from a poplar shoot (I think it's poplar). I fletched with 2 feathers, just tied front and back with waxed linen thread. I mounted them straight, 90 degrees to the nock. After the fact, I see they typically are with the nock. Since I am shooting off a shelf, does it really matter? One quick trial shot was straight and hard. Felt pretty good. What do you think?
