(4) Repair of 301 stitching. Ends of all stitching shall be backstitched or overstitched not less than ½ inch except
where ends are turned under or caught in other seams or stitching. Ends of a continuous line of stitching shall overlap
not less than ½ inch. Thread tensions shall be maintained so that there will be no loose stitching resulting in loose
bobbin or top thread or excessively tight stitching resulting in puckering of materials sewn. The lock shall be embedded
in the materials sewn. When thread breaks, skipped stitches, run-offs, or bobbin runouts occur during webbing stitching
shall be repaired by restarting the stitching a minimum of ½ inch back of end of the interrupted stitching. Except for
prestitching, thread breaks of two or more consecutive skipped or run-off stitches noted during inspection of the item
shall be repaired by overstitching. The stitching shall start a minimum of ½ inch in back of defective area, continue over
the defective area and a minimum of ½ inch beyond defective area onto the existing stitching. Loose or excessively tight
stitching shall be repaired by removing defective stitching without damaging the materials, and restitching in the required
manner. When making above repairs, ends of stitching need not be backstitched.
