How often should I have my sewing machine cleaned and serviced? A. It depends on how often the sewing machine is used and the type of work done on the machine. Cotton fabrics and thread tend to create more lint buildup on your machine. Servicing and cleaning your machine allows the machine to operate smoothly. Also a machine that has been in storage for some time will require servicing as the lubricants can dry up over time.

How come my sewing machine skips stitches? A.You may have a bent or blunt needle, the needle is inserted incorrectly or the pressure on the foot is insufficient.
Why do I keep breaking needles? A.The needle may be inserted incorrectly, you are pulling the fabric while sewing or you may be utilizing the incorrect size needle or thread for the fabric being sewn.
