(1) Restitching. Stitching and restitching made on parachute canopies should be accomplished with size
E nylon thread that is contrasting in color to the fabric being stitched or the original thread 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 should be locked by at least two inches at each end of
a stitch row, when possible. Zig-zag restitching should extend at least 1/4 inch into undamaged stitching at
each end, when possible. Restitch directly over the original stitching and follow the original stitch pattern as
closely as possible.

as prescribed in para 2-17, using size E nylon thread. There is no limit to the number of darns which may be
made on a gore section.

sewn patch or the pressure sensitive patch (iron-on) methods
