Abstract
Abstract A repair tool for performing quick, inexpensive and almost invisible repairs on fabrics which have been subjected to local damage. The tool comprises a base plate having core pins and ring pins projecting upwardly therefrom. An annular holding ring overfits the base plate and sandwiches the fabric to be repaired therebetween. A rotary knob including a circular razor turns within the holding ring central opening to cut a perfect circular hole in the fabric to remove the damaged area. The tool is utilized to cut a similar circular patch from an undamaged portion of the fabric. The patch is then applied to the circular hole in the damaged fabric and is secured thereto by rearwardly positioned adhesive faced material to provide an almost invisible repair.
