Overseas, there is a very creative knitting art.

Remember when I was a child, the sweaters I wore were generally hand - made by my mother. Although they were a bit out of fashion, I still liked them very much. I thought at that time that it was already very difficult to weave a piece of clothing by hand. However, seeing the various things below made of woolen threads, I couldn't help wondering: originally woolen threads can also be used in this way.
