I heard from my friend that Henan Sister Ding’s darning training is very good. It not only has traditional precision darning technology, but also a new technology - machine darning, which is said to be an imitation darning technology and has applied for a patent. The embroidery and repair work is also pretty good. If you search online, you will find that Sister Ding has posted many pictures of shirts, suits, cashmere, sweaters, jeans, and down jackets. I heard from friends that there are two sweater techniques that are not available elsewhere. . I want to go to school, no, I just happened to be searching on the Internet these two days. I will give you a picture for you to look at. Maybe we can become classmates. Hahaha, where are you from?
