Staples are generally made of iron wire, which is coated with nickel or nickel-zinc alloy to prevent rust. FeCSPMnSi and a small amount of Cu are included in the iron wire. The iron content is about 99%. There are many raw materials, such as iron, steel and copper.
For example, the six-pointed star hand crown tutorial:
1. Six staples are combined and buckled into a triangular pattern. After knitting, continue knitting based on the first triangle and use the second equilateral triangle.
2. After adding more triangles in this way, pull it up hard, and it is a six-pointed star. Connect the last triangle with the first triangle to close the six-pointed star.
3. Then continue to do it on the basis of the original six-pointed star, and two will come out. Repeat the above method and continue to do the third and fourth.
4. Next, connect the staple six-pointed stars together.
