Instructions

Back preparation
^^^^^^^^^^^^^^^^

.. note:: Optionally add a molle pattern to the back, to be able to
   attach some removable padding.

   Cut 7 pieces of 25 mm webbing as wide as the back (including
   allowances); starting 6.5 cm from the base put them at one webbing
   width of distance from each other over the bottom back piece.

   Mark a line in the center, and lines at every 4 cm on each distance, and
   sew, backstitching over each piece.

   If desired, sew similar pieces of webbing to the lower part of the
   p
   other panels.

Cut 2 pieces of 50 mm webbing 80 cm long, fold them in half and slide
two wide D-rings in each of them. Sew them in place as close to the
D-ring as possible.

Optionally whipstitch or topstitch the edges of the webbing, making them
a single strap of double thickness.

Sew the webbing pieces to the allowance at the top of the bottom back
piece, at 4 cm from the center.

Cut a piece of 25 mm webbing, 60 cm long, sew it to the allowance at the
top of the bottom back piece, right at the center.

[cut 25 mm webbing for the lower part of the shoulder straps, TBD]

Right sides together, put the top back piece over the bottom back and
sew. Press the allowances up.
