(2) Other parachute items. Stitching and restitching on other parachute Items constructed from cloth, canvas, and
webbing should be accomplished with thread which matches the color of the original stitching, when possible. All straight
stitching should be locked by backstitching at least 1/2 Inch. Restitching should be locked by overstitching each end of
the stitch formation by 1/2 Inch. Zig-zag stitching does not require locking, however, zig-zag restitching should extend at
least 1/4 Inch into undamaged stitching at each end, when possible. Restitching should be made directly over the
original stitching. following the original stitch pattern as closely as possible.
