Tools/materials: belts.
1. Step 1: First, cross the two ends of the belt, fold one end back and press it on the other end.
Step 2: Use the other end of the belt to bypass the front and pinch the tail in half.
3. Step 3: Drill out the tight part of the belt from the circle that was bypassed before, tighten it hard, and flatten the position of the bow.
4. Step 4: Adjust the length after knotting, and an elegant bow will be finished.
