The square knot is useful for binding two identical lines or two ends of the same line around an object for light duty, such as reefing a sail. The square knot can also be used for furling sails, tying cargo straps, and hanging clothes for drying. If the knot looks like two interlocking loops with both bitter ends on the same side of the knot, and both ends of each line exit in the same direction, you’ve done it right.
