You do not use a regular sewing needle when machine embroidering. They make spacific needles for machine embroidery. The ones my dealer suggested are called Organ needles. It is also necessary to use a good quality fabric.
Thin fabric will not allow the embroidery design to lay flat.
The thin fabric will pucker. To get the best results when machine embroidering, it is necessary to use the proper
materials the machines and designs were made for. You will
get a much better finished product.
