When you say embroidery machine, I understand it as repairing embroidery machine. This study takes a little time, about half a year, provided that you have worked as an embroiderer. But if I want to make money with this craft, I think I can earn about 2800 to 3800 yuan a month by studying for more than two years. If I open an embroidery machine accessories shop and help others repair machines, my monthly income should be around 6000 to 10000. (Doing business is risky! )
Board stickers are plate makers, and masters can learn them every month. If you go to work in a factory, it will cost about 3000 yuan. If you open your own plate-making shop, your normal income should be around 5000 yuan. Of course, it's hard to say if you open a bigger shop and hire someone. (Doing business is risky! )
