Buttons are usually divided into two types: practical buttons and decorative buttons.

Generally, there are four eye buttons, two eye buckles, and back single eye buttons.

After four eyes fasten the nail, the front line is "X" or "two" shape. After two eye buttons are well, the line is "one" shape; one eye button is not seen on the front line.

Double buttons should be used for fastening buttons.

After the thread is finished, the needle is put down from the front side of the cloth, so that the knot is left on the surface and covered with buttons. Then, the needle is pushed from the cloth and passes through a buttonhole, then the needle is pushed downward from the front side of the button or relative to the needle, and 3-4 times are repeatedly stitched.

When buttons are fasten, there should be a certain gap between the buttons and the cloth of the clothes, and the feet should be buckled.

The length of the pin is determined by the thickness of the cloth.

The method of twists and turns is to leave the thread behind the button between the button and the cloth, then use the thread to wrap around the foot, generally around the 4-5 circle.

Then sew the needle out of the back, tie it on the line, pull into the interlining of the fabric, and cut out the extra thread.

Decorative buttons only play the role of decoration, so the line should be tightened without having to buckle.
