Add in the desired amount of shooters. This picture is an example of a shooter known as a "nylon" which is essentially a sidewall string in the place of a shooter.

Pro Tip: Shooters placed in different rows create a different feeling when throwing. It's all a matter of trial and error, as well as personal preference to decide where to put your shooters.

Pro Tip: String your shooters different directions to avoid warping of your mesh/pocket over time. Notice how the shooters in this pocket are tied off on different sides.
