The hand-made method of football is very simple.

First, let's find some unused old cloth. It doesn't matter whether the material is soft or not, but it's better not to be too thin, otherwise it won't be strong. Cut out pentagons and hexagons with cardboard. Please note that the side lengths of pentagons and hexagons must be the same. You can measure it yourself. "/>；

Then draw 12 blocks on the cloth according to the pentagonal template, and then cut them. Compare the hexagonal template, draw 20 pieces and cut them later. After painting, cut the picture with scissors and sew it according to the drawing to ensure the joint is firm. After sewing the pattern, sew it like a football. "/>；

Finally, spare parts and cotton plugs are left. Fill the football with cotton, the more the better, the more elastic it is. After filling it out, sew on the last piece. It can be stitched by the seamless method described above. Can kick! Playing indoors does not affect others and makes no noise. "/>；

Football skins are actually made of various materials to obtain better physical properties. Even at 80 miles an hour, football hasn't changed. "/>；
