Eunan, I would love to open up a shop, but with the economy the way it is, and the costs involved, I can't see it happening for me here in MD. The shops that were here, with only a few exceptions are now gone, not enough support! If I was to open one, it would not just be a fly fishing shop! Perhaps someday!
Gator, don't go burning yourself out trying to keep up with some of the rest of us! Many of my boxes have flies in them that are several years old. Properly stored, they don't go bad! Tie what you need, tie when you can & build up the boxes while having fun with it. Otherwise, it will become work & that's one of the things I think most of us try to get away from when we tie!
