When we want to get straight stitches, we can wrap a cloth strip on the right side of the sewing machine so that we can get straight stitches.
When we want to take a fan-shaped surface, we can use a rope to fix the pen at one end, and take the other end as the center of the circle to take the fan-shaped surface.
When we need to sew clothes and don’t want others to see the end of the thread, we can insert the needle into the right side first, and then into the left side, leaving a distance of 1~2 centimeters in the middle, and repeat this cycle until the end of the place we want to mix. Finally, you can hide the thread by pulling it hard.
