(2) Hand darning. When repair of a hole or tear is made by hand darning, the darn should match the
original weave of the damaged material as closely as possible. Hand darning will be performed as follows:
(a) Using an authorized marking aid of contrasting color, mark a square around the damaged area and
ensure that the marking is at least 114 inch back from each edge of the damaged area. The marking
will be made with the warp and the filling of the material.
(b) Using a darning needle and a length of size A or E nylon thread, begin darning at one corner of the
marked area Working in the direction of the fabric warp or filling, pass the needle and thread back
and forth through the material until the opposite diagonal corner of the marked area is reached. (A,
(c) Turn the material and weave the needle and thread back and forth across the stitching made in (b)
above until the hole is completely darned (B, figure 2-38).
(d) If applicable, re-stencil informational data or identification marks as outlined in paragraph 2-19.
