2. Other parachute items. Stitching and restitching on other parachute items constructed from cloth,
canvas, and webbing should be accomplished with thread that matches the color of the original
stitching, when possible. All straight stitching should be locked by backstitching at least ½-inch.
Restitching should be locked by overstitching each end of the stitch formation by ½-inch. 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. Restitching should be made directly over the original
stitching; follow the original stitch pattern as closely as possible.
DARNING
(Refer to Tables 1 and 2, WP 0012 00). Darning is a sewing procedure used to repair limited size holes,
rips, and tears. A darning repair may be made either by hand or by sewing machine, depending upon the
method preferred and the availability of equipment. However, a darning machine should be used to darn
small holes and tears where fabric is missing. A darning repair will be preformed using the following
procedures, as appropriate:
1. Machine darning. Proceed as follows:
a. Using an authorized marking aid of contrasting color, mark a square around the damaged area and
ensure the marking is at least ¼-inch back from each edge of the damaged area.
b. Darn the damaged area by sewing the material in a back and forth manner, using size A or E nylon
thread.
c. Turn the material and stitch back and forth across the stitching made in b., above, until the hole or
tear is completely darned.
