a. Invert canopy and center damaged section on the worktable.
b. Smooth the area around the damaged section; ensure that the radial and diagonal seams are
straight. Place pins through the radial and diagonal seams, as far above and below the damaged
sections as necessary.
c. Remove the damaged section by cutting the fabric ½-inch from all seams, except at the lower
lateral band, where the section can be cut out flush with the lateral band.
d. If the damage does not extend into the corner bounded by the radial seam and the lower lateral
band, cut the fabric diagonally across the corner with the warp or fill, leaving the corner intact.
Leave enough fabric at the corner so that when the new section is installed it will not overlap the
pocket band or V-tab. Adapt the procedures in paragraph 1., above, to complete the section
e. If the damage extends into the corner bounded by the radial seam and lower lateral band, cut and
remove the stitching that holds the V-tab and pocket band (if present). Adapt procedures in
paragraph 1., above, to replace the section. Then sew the V-tab and pocket band in place.
Fold back the raw edges of the trimmed seams ½-inch and baste to the seam with size A, nylon
thread, or ticket No. 24/4 cotton thread.
