This combination of characteristics is essential in a good bait floss, as it ensures that the floss grips onto smooth and hard air-dried hook baits and doesn’t ‘give’ on impact. If the floss is stretchy it could otherwise allow the meticulously prepared, rolled and dried perfectly spherical hook bait to pop out of the loop!
The wax coating on the floss allows anglers smooth knotting and helps ‘blobbing’ of the trimmed knot ends. This burning back of the tags also seals the knot and again this helps to keep the hook bait securely in position, so you can be confident that this critical aspect your presentation is perfect.
Gently heat the floss, by licking the edge of a flame around it, after you have tied on your hook bait (try to do this without burning the pop up!). This makes the floss slightly transparent and shrinks the material, securing the loop in place.
