My three year old daughter loves being around when I tie flies but hasn't yet wanted to try on her own. She likes the colors and the "pretty" Atlantic Salmon flies that I tie and that is probably the most important step in my opinion. Let them be interested and they will pick it up when they are ready. Is a 5 year old ready? I say let him try and if he doesn't like it you can always try again next year.

My son will be born on the 22nd and I think he will be tying wooly buggers by the time that we leave the hospital.

Let us know how he does with the lesson if you let him participate.
