It's very simple, but there is a slight art form to it. Just takes a little practice to get the right amount of glue. All you need are:

The fletching jig of your choice (I recommend either the Greyling or Bitzenburger)

Glue of your choice (Any of the cyanoacrylates work very well....Pine Ridge, Bohning Quantum XT)

Vanes of your choice. If you use Blazers, DO NOT clean the base of the vane first.

Oh, and arrow wraps if you choose.
