And if you do a GREAT job, or even a not-so-great job, you should be able to find a market. Fishermen, especially fly fishermen, are suckers for such things.
Practice with a few. If they turn out okay, take the best and locate a sportsman's store - one that specializes in field and stream, with the emphasis on stream, rather than a basket ball, base ball, etc. type of place.
Offer the owner a commission, or outright sale to him for resale. Don't cheat yourself - research what hand-made or custom made fishing gear goes for. You might just be able to finance your hobby with them.
