Korda recommend you double it up by pulling your baits onto a loop of string and then hand the string over the hook before pulling the top bait back up against the hook to tighten the loop so the loop cannot slip back off the hook in flight. Do not use this product for tying the hair up tight to the hook, if it is pulled too tight the water cannot attack the PVA strands in the middle of the braid and the knot may remain.
