I'm just starting out. I need to buy flies. I have been through a book about fly fishing in my area (Maryland) and have a list of 16 or 17 different patterns in 2 to 3 sizes for each pattern. That's 32 to 51 flies if I just buy one of each. Not to mention a couple that I can't find. So how many do I buy? One of each? 2? There is one web site where you buy a dozen at a time. While their prices look great, the start up cost is daunting. Any help would be appreciated.
