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, 70 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]
Cut two pieces of 25 mm webbing, 70 cm long, put them on each strap
support so that one edge goes from one corner to the middle of the long
side and there are 5 cm of webbing beyond the long side.
Fold the strap support in half, right sides facing, and sew at 1 cm from
the long edge.
Turn inside out, topstitch all around the webbing.
Put the strap support on top of the bottom back, 5 cm from the bottom,
with the webbing facing up, and sew in the allowance.
Trim the excess webbing.
Right sides together, put the top back piece over the bottom back and
sew. Press the allowances up.
