first, clean the sweater and dry it. Then cut a large piece of cardboard to be slightly larger than the current sweater body for use. Then put the cut cardboard into the sweater and lay it flat on the desktop. The sweater will stretch a little because of its elasticity. At this time, put a slightly moist towel on the top of the clothes, and iron it with a steam electric iron about two centimeters away from the sweater. Be careful not to iron it directly, which will damage the wool fibers. While ironing, shape the sweater with the other hand, so that the sweater can be restored to its original better shape with both hands.

2. local heating at high temperature.

For the lengthened part, soak it in hot water of 7-8 degrees for about 2 minutes, or locally heat it with hot water steam just poured into the thermos bottle. Similarly, gently adjust the shape, and the effect is good after repeated times.

3, high-temperature steaming.

if the whole sweater becomes loose and long, you can soak it all, wrap it in a bath towel, steam it in a pan for about 2 minutes, and lay it flat to dry. The shrinkage effect is also very good.

4. soak in warm water first, and then soak in cold water.

If your woolen sweater is pure wool, you can soak it in warm water of 3-5 degrees for about 1 minutes, and let it slowly recover its shape until its shape is almost restored, and then put it in cold water for setting. Finally, remember not to wring it out when drying, but to dry it flat.
