Tie the sleeves tightly with a rubber band (or thread) first, and then iron them gently with a steam iron. When they are dry, they will become tight.

Second, iron the sweater with hot water, the water temperature is preferably between 70℃ and 80℃. If the water temperature is too high, the sweater will shrink too small. If the cuffs or hem of the sweater lose elasticity, it can be soaked in hot water at 40℃~50℃, 1~2 hours later, and the sweater can be shrunk.

3. Wrap the sweater with a clean white towel, put it in the steamer of the rice cooker, steam it for 10 minutes, take it out, shake it hard (but not too hard, otherwise the sweater fibers will straighten out and deform), then carefully pull the loosened sweater into its original shape, put it flat on the thin plate (if there is a sieve, you can put it on the back of the sieve), clamp it around with a clothes peg and put it in a ventilated place.
