Stitching and Restitching. Perform stitching and restitching as follows, referring to tables 2-2 and 2-3:
(1) Parachute canopy assemblies. The stitching and restitching made on parachute canopies should be
accomplished with thread that is contrasting In color to the fabric being restitched. If contrasting color thread is not
available, thread of matching color may be used, providing all other specifications are met. Straight stitching and
restitching on parachute canopy assembles should be locked by at least 2 inches at each end of a stitch row, when
possible Zig-zag stitching does not require locking, however, zig-zag restitching should extend at least ¼ inch into
undamaged stitching at each end, when possible. When restitching parachute canopy assemblies, stitch directly over the
original stitching and follow the original stitch pattern as closely as possible.
