The bows are made of ribbon or fabric and are tied into a looped knot. They are then attached to the tree with ornament hooks, which are small pieces of wire with a loop at one end. The bows can be made in a variety of sizes and colors, adding a festive touch to the tree. To make bows, you'll need some ribbon or fabric, ornament hooks, and scissors. Start by cutting the ribbon or fabric into a square, then fold it diagonally to create a triangle. Take the two ends and bring them together to make a loop. Twist the loop around to create a knot and then pull tight.
