zigzag sewing machine, the specifics cited in the

applicable item equipment publication, and the following

procedures.

stitch width.

(2) Beginning at a point 1/4 inch beyond one

end of the cut or tear, stitch lengthwise along the

damaged area to a point 1/4 inch beyond the opposite

end of the cut or tear (A, fig. 3-3). The cited stitching

procedure will also apply to an L-shaped cut or tear (B).
