Making a knot in something is a common task that requires TYING two ends together. TYING is the process of connecting two objects or pieces of material together by looping a string, rope, or other material around them. This can be done in a variety of ways, such as making a knot, using a knotting technique, or using a knotting tool. Knots are often used to secure items, such as TYING a rope around a tree branch or TYING a rope around a bundle of items. Knots can also be used to join two pieces of material together, such as TYING a rope around a piece of fabric or TYING a rope around a bundle of sticks.
