Is fly tying difficult? I know that's probably a really silly question but from an outsider looking in, I'm wondering about the learning curve and how much time (and wasted supplies) I would need to devote to the art before I could consider myself proficient. I am willing to dedicate time, just curious how long I would need to be at it before I could tie anything the fish wouldn't laugh at. Also, Is this an expensive hobby? Right now, I buy my flies from shops. I have a feeling tieing your own saves money in the long run but I'm not sure about initial startup costs, could anyone shed some light on this please? Thank you! Sorry for the silly questions, just a noobie trying to soak up as much as I can.
