Abstract
The bottom plate of a cloth presser supporter is pivotally mounted on a lower end of the supporter adjacent a rear end of the plate. The plate has an L shaped slot, one slot leg being a needle location groove, the other slot leg being a needle thread guide. The plate has a knife receiving groove with a knife mounted therein. A thread holder holds the end of a thread vertically above the plate so that the thread when extended between the held thread end and the first zigzag stitch of the thread does not extend over a corner defined by the intersection of the side wall of one slot leg with the corresponding side wall of the other slot leg.
