Abstract
A detachable and slideable fabric guide is used in combination with a sewing machine and adapted to bridge a sewing machine bed of a certain width, the fabric guide comprising an elongated main body made of an elastic material with sides which comprise vertical opposite faces, at least one of which is used to contact a fabric edge during stitching operation. The opposite ends of the main body are respectively curved down to integrally form hook portions which are, terminated with opposite abutments or grips each extending laterally of the main body. The opposite abutments normally define therebetween a predetermined distance a little smaller than the width of the sewing machine bed, which distance may be enlarged due to an outward flexing of the hook portions. One of the vertical faces of the main body is provided with a pair of walls protruding laterally therefrom to define therebetween a groove extending the substantial length of the elongated body.
