This kind of problem is quite common. In fact, if it is obtained from a professional fur processing company, it is estimated that it will cost 50 yuan. Actually, they stitched it up for you by hand. There is no skill.

Instead of this, it is better to find a thread of the corresponding color and sew 2 stitches with a needle and thread. This is actually ok. I can't tell from the outside.

There is no need to send it to be repaired.
