Preparation materials: a needle, a winding thread and a pair of scissors.

1. Put the button to be sewn in the proper position and align it with other buttons.

2. Insert the needle upward from under the cloth, pass through the buttonhole, and pull out the thread completely.

3. Then go through an opposite buttonhole from top to bottom of the cloth, and pull out the thread completely. At the same time, it is best to keep the button still.

4. If two eye buttons are used, thread the needle through the first eye button again, and if four eye buttons are used, thread the needle through the third eye button.

The picture shows a four-eye button, and we can sew the thread into a cross. Repeat this process until the button is fixed.

6. When you feel that the button has been fixed, put the last needle through the cloth from the bottom, but don't go through the eye of the needle again.

7. The thread between the button and the cloth (just sewn up and down) goes back and forth five or six times, and then it is tightened to increase the firmness.

8. Then thread the needle from the top to the bottom of the cloth.

9. Sew three or four stitches back and forth on the fabric on the back of the button.

10, tighten and cut off the excess parts, so that the button is sewn.
