The purpose of the Navy square knot is to bind items or secure items against a curved surface. A Navy square knot is not to be used when serious safety is required. This knot is great for uses in camping, sailing, crafting, or decorating. The only item required for the Navy square knot is a single piece of rope with a length of your choice.
Place the rope around your items
Place the rope around the items you want to secure together. Make sure the length of the rope is still long enough to fold over itself twice.
Begin the knot
Hold each end of the rope in each hand. Pass the right end under and over the left end. Pass it under the left end again. The right end of the rope is now in your left hand, and the left end is now in the right hand. Pull the ends lightly.
Repeat the process
Pass the original right end of the rope under and over the original left end of the rope. Pass it under the left end one more time. The right end is back in your right hand, and the left end is back in the left hand. Pull lightly to complete the knot.
