+Parallelepipedal Zippered Pouch
+===============================
+
+.. only:: html
+
+   .. contents::
+
+.. figure:: closed_pouch.jpg
+   :align: center
+
+This is a semi-rigid rectangular pouch suitable as a carrying case for
+handheld devices, but also as a pencil case or packing cube.
+
+View A has padding (or rigid plates) at the top and bottom, view B uses
+a padded lining to also give some protection to the sides.
+
+Materials
+---------
+
+The amounts of materials needed depend on the size of the pouch: smaller
+sizes will probably come out easily from leftovers from other projects,
+but print out the pattern to be sure of the amounts needed before buying
+new fabric.
+
+Fabric
+^^^^^^
+
+For both views:
+
+* sturdy outer fabric: canvas, cordura;
+* optional: mesh or lining fabric for the pockets;
+* optional: fabric for piping: similar to the lining fabric for view A;
+
+for view A:
+
+* lining fabric: plain cotton print, ripstop, lighter cordura;
+* padding material: thick interfacing;
+
+for view B:
+
+* padded lining: 2-3 mm thick neoprene or 3d mesh.
+
+Notions
+^^^^^^^
+
+* a zipper as long as piece C in the pattern;
+* bias tape or other lightweight binding for the raw edges;
+* piping cord;
+* optional: elastic binding for the mesh pockets;
+* optional: 2.5 cm wide webbing;
+* matching sewing thread.
+
+Pattern
+-------
+
+Get the valentina pattern :download:`zippered_pouch.val` and enter the
+measurements in the Variables Table.
+
+You have to set the following increments for the *inner* size of the pouch:
+
+``#inner_x``
+   the width, i.e. the lenght of the side where the hinge will be;
+``#inner_y``
+   the lenght, i.e. the other side of the top;
+``#inner_z``
+   the height or thickness, i.e. the side that is partially taken by the
+   zipper;
+
+and the other increments:
+
+``#ease``
+   amount of ease added twice to each measurements to get the outer
+   measurements: if you're using a thick lining make sure to provite for
+   it in here;
+``#zipper``
+   the width of zipper that will be visible in the final pouch: teeth
+   plus a bit of fabric on each side;
+``#sewing_allowance``
+   the sewing allowance you want to use.
+
+For convenience, these are some pre-configured patterns, as a printable
+PDF or valentina layout:
+
+* 20 cm × 20 cm × 4 cm :download:`20x20.pdf`
+  :download:`20x20_layout.vlt`;
+* 10 cm × 10 cm × 1.5 cm, using just the zipper for the sides
+  :download:`10x10.pdf` :download:`10x10_layout.vlt`;
+* to measure as a carrying case for the Pyra_ handheld
+  :download:`pyra_case.pdf` :download:`pyra_case_layout.vlt`.

+
+Instructions
+------------
+
+Cutting
+^^^^^^^
+
+Cut 2 of piece A, 1 of piece B and 1 of piece C from the outer fabric.
+
+For view A also cut the same pieces from the lining, and 2 of piece A1
+from the interfacing.
+
+For view B cut 2 of piece A, 1 of piece B1 and 1 of piece C1 from the
+lining.
+
+Also cut all pieces for the pockets.
+
+Lining preparation
+^^^^^^^^^^^^^^^^^^
+
+Sew all internal structure to the lining pieces A
+
+Half or 4/5 pockets
+"""""""""""""""""""
+
+For each 4/5 or half pocket you want to add, cut one of piece D1 or D2
+respectively in netting or pocketing.
+
+.. figure:: 020101-bound_mesh.jpg
+   :align: center
+
+Bind the top edge of the piece.
+
+.. figure:: 020102-half_pockets.jpg
+   :align: center
+
+Put the piece on top of a lining face, wrong side of the piece on the
+right side of the face piece, and machine baste around the border, in
+the sewing allowance, backstitching over the bound edges.
+
+Optionally sew vertical lines to divide the pocket, starting from the
+bound edge and backstitching over it.
+
+Treat as one with the face lining piece.
+
+Zippered pockets
+""""""""""""""""
+
+For each zippered pocket you want to add, cut one of piece A in netting
+or pocketing.
+
+Put a zipper, as long as the width of the pouch, at about 3/4 of the
+height of the piece, wrong side of the zipper on the right side of the
+piece. Sew near the zipper teeth.
+
+Carefully cut the piece below the zipper, fold the allowances out, and
+topstitch again with a zig-zag stitch over the zipper tape, catching the
+allowances.
+
+Put the piece on top of a lining face, wrong side of the piece on the
+right side of the face piece, and machine baste around the border, in
+the sewing allowance.
+
+Treat as one with the face lining piece.
+
+Outer faces
+^^^^^^^^^^^
+
+.. figure:: 030101-webbing.jpg
+   :align: center
+
+Cut strips of webbing that are as long as the width of the pouch, put
+them at one webbing width of distance from each other and sew every 4 cm
+to make a MOLLE-compatible pattern.
+
+view A
+""""""
+
+Put piece A lining with the wrong side up, then piece A1 padding and
+piece A fabric with the right side up, machine baste all around the
+edges in the sewing allowances.
+
+Treat as one.
+
+view B
+""""""
+
+.. figure:: 030301-pieces_a.jpg
+   :align: center
+
+Put piece A fabric on piece A padded lining, wrong sides together,
+machine baste all around the edges in the sewing allowances.
+
+Treat as one.
+
+Sides
+^^^^^
+
+View A
+""""""
+
+Sandwich the zipper between piece C fabric and lining, right sides
+together, making sure to align the allowance in such a way that when the
+seam is folded back the resulting piece will be as tall as piece B.
+
+Sew the long seam, press it so that the wrong sides of fabric and lining
+touch each other, and the zipper comes out of the fold.
+
+Machine baste the free edges of the fabric and lining together, treat as
+one.
+
+If the zipper has free ends, finish it on both ends with a metal stopper
+or by sewing a few times over the teeth.
+
+Sandwich the side between the pieces B of the fabric and lining, right
+sides together, sew.
+
+Roll up the side so that the other short edge is aligned with the short
+edges of the hinge, still right sides together, sew.
+
+Turn inside out pressing all of the allowances towards the hinge.
+
+View B
+""""""
+
+.. figure:: 040201-bound_padded_lining.jpg

+
+Bind the top edge of piece C1 padded lining and the side edges of piece
+B1 padded lining.
+
+.. figure:: 040202-sewn_zipper_outer.jpg
+   :align: center
+
+Put the zipper on piece C fabric, right sides together, sew with the
+right allowance so that when the seam is folded open the resulting piece
+will be as tall as piece B.
+
+Press the seam with both allowances towards the fabric.
+
+.. figure:: 040203-sewn_lining.jpg
+   :align: center
+
+Put the padded lining on top of the fabric, wrong sides together, so
+that the bottom edge is aligned; pin it to the allowances, open the seam
+and sew the lining to just the allowances of the fabric and zipper.
+
+.. figure:: 040204-sides.jpg
+   :align: center
+
+Put the lining back wrong sides together with the fabric, machine baste
+the free edges and treat as one.
+
+If the zipper has free ends, finish it on both ends with a metal stopper
+or by sewing a few times over the teeth.
+
+.. figure:: 040205-hinge_outer.jpg
+   :align: center
+
+Put the side on piece B fabric, right sides together, sew one short
+edge, then align the other one and sew that too.
+
+Press the allowances towards the hinge.
+
+.. figure:: 040206-complete_sides.jpg
+   :align: center
+
+Put the padded hinge over the hinge, wrong sides together, and sew it to
+the allowances on both sides.
+
+.. figure:: 040207-sides_as_one.jpg
+   :align: center
+
+Machine baste the top and bottom of the hinge, and treat the full sides
+as one.
+
+Piping
+^^^^^^
+
+.. figure:: 050101-piping.jpg
+   :align: center
+
+Prepare two strips of piping and baste them to the top and bottom of the
+sides, putting the joins close to the seams of the hinge.
+
+Assembly
+^^^^^^^^
+
+.. figure:: 060101-sewing_top_face.jpg
+   :align: center
+
+Right sides together, put the top face inside the sides, near the
+zipper, carefully sew all around. You may want to sew part of the front,
+cut the thread, move the zipper sliders out of the way and sew the rest
+of the seam.
+
+.. tip:: when sewing keep the face on top and the sides at the bottom,
+         and ease the excess fabric rather than having to pull on
+
+Put the other top face right sides together inside the sides, making
+sure that the zipper is at least partially open, sew all around.
+
+Fully open the zipper, turn inside out and check that all seams are ok.
+
+.. figure:: 060102-binding.jpg
+   :align: center
+
+Turn inside out again, sew binding on the remaining raw edges.
