In general flat embroidery, the speed of embroidery machine should be 850 revolutions per minute.
However, due to the complexity of the process and the thicker fabric, the speed should be set to 600-650 revolutions per minute for three-dimensional embroidery and leather embroidery.
When preparing for leather embroidery, two layers of wax paper should be placed under the leather, which can make the needle move more smoothly and the embroidery effect will be better.
However, the amount of wax paper needed to be placed depends on the type of leather. As for flat embroidery and three-dimensional embroidery, paper or transparent glue can be placed.
