Sewing requirements will vary according to the type of item being repaired and the type of

stitch pattern, if applicable, required to accomplish a sewing procedure will be specified in the
paragraph applicable to the item being repaired. All original stitching that is cut during the
performance of a sewing procedure will be removed from the applicable item. Immediately

a.
Basting and Temporary Tacking. Basting and temporary tacking are hand-sewing methods used to temporarily
hold layers of cloth fabric together while a repair is being performed. The following is a list of procedures which apply to
basting and temporary tacking actions:
(1)
Basting and temporary tacking should be made using thread which is of a contrasting color to the material
being worked.
(2)
On small cargo parachute canopies, basting will be made using a single strand of size A nylon thread or
ticket no. 24 cotton thread.
(3)
When basting, do not tie knots at any point in the thread length. Also, the sewing should be made with two
stitches per inch.
(4)
Temporary tacking will usually be made using a length of size E nylon thread (item 29, appendix D).
However, an alternate type thread may be specified within-the paragraph applicable to the item.
(5)
Immediately upon completion of a repair, remove previously made basting or temporary tacking stitches.
