Problems solved by technology

The stitches of single-thread sewing are in the form of chain sleeves, and once they come out of the thread ends, they are easily separated, which is the biggest disadvantage of single-thread sewing
In addition, during the operation of these manual miniature sewing machines, some operations are not flexible, often jammed threads, and the sewing effect is rough.
