Glad to answer your question: cotton-padded jacket, a man with a drawstring tied around his waist, looks like this: leave a suitable length for the drawstring. Adjust the appropriate folding point and fold the reserved drawstring upward. Use the end of the drawstring to press the drawstring trunk and make a circle. When winding in a circle, don't wind it too tightly or too loosely, otherwise it will be unsightly. When winding to the end, put the cable head into the coil that starts to be folded back. Gently pull the drawstring suitcase to tighten the knot.
