How to change the collar of pullover sweater into a small round neck?
The first method is threading and ironing. This method first prepares a worn-out silk stocking, then draws out the silk thread that exceeds the circumference of the neckline from the silk stocking, and then puts the drawn silk thread on the loose neckline part bit by bit, generally 1.5cm above the neckline seam of the high collar. After threading the silk thread to the neckline, tie it tightly, and then scald it with steam. Before ironing, put a wet towel on the clothes, so that the clothes won't be burned. Finally, untie the silk thread, so that it can be restored to its original state and the neckline of the pullover will be smaller. The second method is hot water ironing. First of all, we use a rubber band to tie the neckline of the sweater, and the tightness is moderate. The tie is above the neckline sewing line 1.5 cm. Then we iron the neckline with hot water of 70-80 degrees for five minutes. Finally, we spread the sweater flat to dry, and the neckline will recover after drying. This method is actually somewhat similar to the first method.
The third method is neckline ironing, which is simpler than other methods. Just tie the folded neckline with a rubber band, then spray it seven or eight times every two centimeters with a steam iron, and then ventilate the sweater to dry, so that the enlarged neckline will slowly recover. If you don't have a steam iron at home, you can also use the steam in a thermos just filled with hot water to achieve this effect. The fourth method is to sew the elastic band inside, that is, buy an elastic band, make it into a circle, put it in a loose fur collar, and then turn the high collar upside down to block it.
There are many ways to shrink the neck of pullovers, and there is not only one. I only gave four examples.
