A manual feed is used primarily in freehand embroidery, quilting, and shoe repair. With manual feed, the stitch length and direction is controlled entirely by the motion of the material being sewn. Frequently some form of hoop or stabilizing material is used with fabric to keep the material under proper tension and aid in moving it around. Most household machines can be set for manual feed by disengaging the drop feed dogs. Most industrial machines can not be used for manual feed without actually removing the feed dogs.

The most common cause of this is improper threading. 1. Thread the upper thread properly with the presser foot in the UP position. 2. Make sure the bobbin is threading with the thread unspooling in the correct direction. 3. Make sure the needle and thread are suitable for the fabric in your project. Watch this video.
