 Back preparation
 ^^^^^^^^^^^^^^^^
 
-Cut 6 pieces of 25 mm webbing as wide as the back (including
-allowances); starting 11.5 cm from the base put them at one webbing
-width of distance from each other over the bottom back piece.
+.. note:: Optionally add a molle pattern to the back, to be able to
+   attach some removable padding.
 
-Mark a line in the center, and lines at every 4 cm on each distance, and
-sew, backstitching over each piece.
+   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.
 
-[cut 50 mm webbing for the shoulder straps, baste to the same piece]
+   Mark a line in the center, and lines at every 4 cm on each distance, and
+   sew, backstitching over each piece.
 
-[cut 25 mm webbing for the closure, baste to the same 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]
