Tying the Hair Rig: Step 3 - Rigging to the Main Line

You could tie the end of the braid directly to the main line, but I don't recommend it.  The best way to connect the braid to the main line is to use a barrel swivel with an interlocking snap.  See below.

Here's a closer look.

You'll want to use an improved fisherman's knot to attach the end of the swivel without the snap to the main line.  

Don't tie anything directly to the end of the swivel with the snap or to the snap itself.   Instead, you'll tie a loop knot at the top of your braid.  See below.

Please forgive the rudimentary level of the hair above.  It was one of the first I tried, and it taught me  NOT to use a hook with barbs.  Nonetheless, you can see the loop I made at the top of the braid.

Using that loop on top allows you to form hairs with several different hooks and then switch them out in a snap, literally.  See below.

Remember, unlike what's shown in the pics above, use a barbless aka plain shank hook.

Tight lines!
