Abstract
A device controls the speed of needle movement in a sewing machine and thus the stitch length based upon the movement of a motion detection device relative to a reference surface. The formation of stitches by the sewing machine is controlled by detected changes in position of the detection device relative to the reference surface in connection with a predetermined stitch length setting and starting speed, set on either the detection device, an adapter or as part of the sewing machine control. The detection device may move together with the article being sewn while the sewing machine and reference surface remain stationary, or the detection device may move with the sewing machine while the article that is being sewn and reference surface remain stationary.
