Welcome to the Baby Lock Cover Stitch Machine Your Baby Lock Cover Stitch machine provides a variety of chain and cover stitches, allowing you to create professional looking hems just like the readytowear fashions in stores. A variety of stitch widths and lengths also provide options for creating the look you want.
How Your Machine Operates Awareness of its simple operation will enable you to become more proficient in its use. Please read all instructions before using your new machine. Use one, two or three chain/cover stitch needles and one looper for a chain or cover stitch. When forming a chain stitch, the chain needle thread catches the chain looper to form a straight stitch on the top of your fabric and thread chain loops on the underside.
