I was pretty self efficient already at the age of 5 years old. Both of my parents have been bow hunting for years so It was something I grew up with. I was always in the Archery shop with dad helping and learning while tinkering with bows and with arrows, broad heads, fletching, etc! I haven't done my own fletching for 10 years or so but I plan on doing my own again being every time I get a dozen new arrows the fletching is coming off with in 3 to 4 months if I'm lucky.
