Button neck wrapping is performed in a manner closely simulating "hand" sewing. After sewing both a stay button and a surface button to a workpiece, a sewing table makes a circular motion while keeping a needle entry as the center, and a thread is slidably clamped and guided to pass through a guide hole tentatively formed underneath a needle such that the thread wraps firmly around the button neck.
