Knots for kite flying

The five knots illustrated below are some of the most useful ones for kiteflying.

Use an Overhand Knot to create a loop at the end of your stunt kite flying lines:

Use a Lark's Head Bridle Knot to attach your flying lines to the bridle of your stunt kite:

If you purchased bulk Dacron line, transfer it to your reel and use the Slip Knot to attach it to your reel:

Slip Knot: Tighten second overhand knot up against first one.

If you have a swivel, tie your line to it using a Clinch Knot:

Clinch Knot: Use 5 wraps and this knot will have 90% of the strength of your line.

If you don't have a swivel, tie the line to your kite with the Bowline Knot:

Bowline Knot: It won't come untied under tension and has 85% of the strength of your line.
