I heard from friends that Ding Jie's darning training in Henan is very good, not only the traditional precision darning technology, but also the new technology-machine darning, which is said to be imitation darning technology, and has applied for a patent. Embroidery sewing is also good. Search online, Ding Jie sent a lot of pictures, shirts, suits, cashmere, sweaters, jeans, down jackets. According to a friend, there are two kinds of sweater techniques that are not available elsewhere. I want to know everything I said. No, I just searched online these two days. I'll give you a picture. Maybe we can be classmates. Hehehe, where are you from?
