1. Turn on the electric iron and get wet for ironing. The electric iron should be set to the highest temperature. Wet your towel or handkerchief with tap water. Don't wet the veil, just wet it a little.

2. Prepare pants. You can pull the belt to the desired length and then fix it on the ironing board with a pin, or put the belt directly on the ironing board until the belt is stretched to the appropriate width.

3. Cover the wet cloth on the elastic band. The wet cloth must completely cover the elastic band to be stretched. If necessary, prepare two pieces of cloth.

4. Iron the elastic band. When the electric iron is heated to the highest temperature, the elastic band is covered with a wet cloth and ironing can begin. Ironing 10 second, stop 10 second, and iron alternately for 5 to 10 minute. This method can make pants fit better, because high temperature can increase the breaking strength of elastic band. That is, the elastic band can be stretched for a longer time before breaking.

5. Prepare a chair. It would be great if you could find a chair of the right size to stretch the elastic band. If you can't find such a chair, you can also stretch the elastic band with one side of a small table, an empty drawer or an empty photo frame.

6. Put the elastic band on the chair. If possible, align the two sides of the belt with the two sides of the back of the chair, so that the tension of the elastic band is even.

7. Keep it that way. You can leave it on for 24 hours after wearing the belt. If you are still not satisfied with the tightness of your trousers after 24 hours, put them back on the chair and take them off after a few days. It is best to put the chair in a warm place, so that the stretching effect will be better.
