I usually pre-tie 12-15 before heading out.
- I use Berkeley 4" bubble gums.
-Start with a 3' leader (as you will lose some after threading and knot),
-First tie an egg loop knot( I usually use size 2 or 4 owner super needle points),
-Egg loop is in case you need to add yarn,
-Slide a size 4 bead(red, orange or white worked for me),
-Use a needle and thread your worm to your leader, starting about an inch above the tail and get the needle out from the head( this is the part you need to be careful not to break the worm with needle)
Good luck.
