Quick Answer
You can build a paracord fishing line with added strength by using a reinforced core and incorporating additional materials.
Preparing the Core
To create a paracord fishing line with added strength, start by preparing a core made from a durable material such as braided or monofilament fishing line (0.10 mm to 0.20 mm diameter). Cut a section of the core material and tie a knot at one end to prevent it from fraying. This core will provide the foundation for your paracord fishing line.
Wrapping the Paracord
Cut a section of 550 paracord (or equivalent) approximately 10 times the length of the core material. Begin wrapping the paracord around the core, overlapping each turn by about 50% to ensure a secure bond. Continue wrapping until you have used up the entire length of paracord, leaving a small tail for securing the end.
Reinforcing the End
To add additional strength to the end of the fishing line, tie a series of overhand knots (4-6 knots) around the core, leaving a small loop at the end for attaching a lure or hook. To prevent the knots from coming undone, dab the knot with a small amount of clear nail polish or thread sealant. This reinforced end will provide a secure attachment point for your fishing gear.
