First, soak in hot water.
Sweaters become loose after wearing, which not only doesn't fit but also affects the appearance. At this time, you can soak the sweater in hot water to restore the sweater to its original state. Be careful that the water temperature is not too high, about seventy or eighty degrees, then soak the sweater for an hour, and then take it out and soak it in cold water for ten minutes.
Second, high-temperature ironing sweater stereotypes
High temperature will change the elasticity of the sweater, so we can use an electric iron to shape the sweater at high temperature after it becomes slack. Note that before ironing, measure the length of the neckline, then sew a circle around the neckline with a needle and thread from the end of the neckline, then iron the neckline with an ironing machine for five minutes, and finally untie the needle and thread.
Third, sew the loose position with needle and thread.
The places where sweaters are easy to relax are neckline, cuffs and hem. Those more relaxed places can be decorated with needle and thread. Sew the first stitch on the side line about 5 cm away from the hem, and then sew the two sides in turn, and the spacing gradually becomes larger, forming a situation in which the upper stitch spacing is smaller and the lower stitch spacing is larger. After sewing, pull the wire and hide it. Similarly, the position of neckline and cuffs can also be modified and reduced.
