+Shoulder Sack
+=============
+
+.. figure:: sack.jpg
+   :align: center
+
+This bag style is, I believe, pretty common among reenactors of epochs
+between the Middle Ages and the 18th century, and I've found online a
+`list of period depictions of similar bags
+http://www.larsdatter.com/wallets.htm>`_ .
+
+It is a convenient style of bag that can be used to carry clothing and
+other goods.
+
+These instructions aren't historically accurate, but at least the one
+sewn by hand are vaguely plausible, since they use stitches and
+techniques with a long history.
+
+The instructions for machine sewing give a bag with visible machine
+stitching that is probably not appropriate for any reenactment, but are
+suitable for an historically-inspired variant made with modern technical
+fabric.
+
+Materials
+---------
+
+* Less than 1 m sturdy linen or cotton fabric, or lightweight waterproof
+  syntetics;
+* matching sewing thread.
+
+Pattern
+-------
+
+This bag is made out of a rectangle of fabric as high as the lenght and
+twice as wide as the width of the finished bag, plus sewing allowances
+on all four sides.
+
+To hang confortably from the shoulder a lenght of about 1 m looks good,
+and if you're using narrow fabric (~80 cm) using the full width is
+convenient.
+
+Instructions by Hand
+--------------------
+
+Fold down all four edges of the fabric by the sewing allowance twice to
+form a hem, sew with a running stitch.
+
+.. tip:: for thick fabric that does not unravel folding the edge just
+   once may be enough.
+
+Whipstitch together two long edges for 3/8 of the length from each end,
+leaving a slit in the middle that is 1/4 of the full length.
+
+Fold the fabric so that the long seam + slit is in the middle, and
+whipstitch closed the short edges.
+
+Instructions by Machine
+-----------------------
+
+.. tip::
+
+   If using coated, water repellent fabric, you want to minimize holes,
+   so use a longer stitch than usual (e.g. 3 mm) and avoid using pins as
+   much as possible, only using them in the sewing allowances.
+
+   Do however backstitch at the start and end of all seams, for
+   stability.
+
+   Binder clips are useful to keep things in place without making holes,
+   even if they can't do miracles on extra slippery fabric like
+   silnylon.
+
+Right sides together, align the long sides of the fabric and sew with a
+double sewing allowance 3/8 of the lenght
+
+Fold down all four edges of the fabric by the sewing allowance twice to
+form an hem, topstitch.
