After each use, make sure that you put a cover over your sewing machine. How you do this is up to you. Many people cover their sewing machines with blankets, homemade covers, or bed sheets. Others opt to use a sewing machine case. Regardless of your preference, doing this brings some great benefits. It will keep dust and other debris from collecting on it. It will also protect the various mechanical and electrical parts free from harm by pets, children, and objects in your home.
