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. 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.
