Lets see, plans...
Uhmmm, round to oval shape tube...made of medium weight leather.
Length, about as long as your arrows minus 4 to 6 inches...
Piece of wood for a bottom plug...DO NOT rely on any type of bottom that is only leather. Broadheads can cut through too easily. Especially if you are going through thick stuff and the nock hangs up on a limb and you put pressure on it because you are moving. Trust me, I know about that one... Shoved a broadhead about 4 inches down through the bottom of mine once. :eek:
One shoulder strap... adjustable.
Optional: belly/chest strap to help keep it in place if you prefer it that way.
Yup, that'll do...
And really, that's about all there is to it.
