The taut line hitch is an adjustable loop-type knot for lines under tension. This knot is perfect for tying guy lines to pegs or any place you need to adjust the tension. A fairly easy knot to tie and a very handy one to know.
How to tie the taut line
Make a turn around a post or other object several feet from the free end.
Coil the free end twice around the standing line working back toward the post.
Make one additional coil around the standing line on the outside of the coils just made.
Tighten the knot and slide it on the standing line to adjust tension.
