The steps of self-treatment are as follows:
Spare materials: scissors, same color needle and thread, lighter.
1, find out the position of running cotton.
2. If it comes from the gap of the thread, just cut the cotton directly.
3. If it is found that the pore of cotton cloth is larger than the diameter of some cotton wool inside, and the cotton wool is separated out, then find out the position of the thread end.
Just sew with the same color thread and needle and thread.
5. After sewing, take a lighter to bake off the extra thread, so that the thread will be stronger.
