The present invention provides a fabric tensioning device for stretching fabric on a sewing machine. The fabric tensioning device includes a cylindrical frame having a window extending in a longitudinal direction. A fabric clamping member clamps down the cloth material against the frame for presenting the material to the embroidery needle at the window in a tensioned state. The clamping member opens and closes on the frame and has a pair of opposing fabric clamps on the left and right side of the frame that are oblong in the longitudinal direction with open front edges. The fabric clamps are tightened against the frame by belts in the front and rear thereof.
