Attaching the leather-ish protection to the bottom +needs to be done by hand, however. + +Materials +--------- + +Fabric +^^^^^^ + +* 1 m outer fabric (e.g. waxed canvas); +* 1 m lining fabric (e.g. lighter canvas); +* 30 cm leather-like material for reinforcements. + +Notions +^^^^^^^ + +* 2.1 m 25 mm webbing; +* 1.6 m 50 mm webbing; +* 4 50 mm D-rings; +* 2 25 mm D-rings; +* glue suitable for the leather-like material; +* strong sewing thread; + +Pattern +------- + +Download the pattern from :download:`roll_top_backpack.val`. + +The file is set up to only print the pattern pieces for the bottom, +strap support and webbing cover, also available as a tiled PDF in A4 +format: :download:`roll_top_backpack-A4.pdf`; everything else are just +rectangles, and their measurements can be taken from the Variables Table +in valentina. + +Instructions +------------ + +Cutting +^^^^^^^ + +Cut all pieces as indicated on the patter, either the basic pieces or +the ``bc`` variants if making the `Box Corners`_ variant. + +Back preparation +^^^^^^^^^^^^^^^^ + +.. note:: Optionally add a molle pattern to the back, to be able to + attach some removable padding. + + .. figure:: 0200-molle_back.jpg + :align: center + + 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 + other panels. + +.. figure:: 0201-webbing_straps.jpg + :align: center + +Cut 2 pieces of 50 mm webbing 80 cm long, fold them in half and slide +two wide D-rings in each of them.

Press the allowances up. + +Front preparation +^^^^^^^^^^^^^^^^^ + +.. figure:: 0301-preparing_front_closure.jpg + :align: center + +Cut 10 cm of 25 mm webbing, put two D-rings in it, fold it in half and +sew as close to the rings as possible. + +.. figure:: 0302-whipstitching_front_closure.jpg + :align: center + +Optionally whipstitch the two sides. + +.. figure:: 0303-front_closure_placement.jpg + :align: center + +Put it in the center of the front piece, in such a way that the top +of the D-rings aligns just below the level of the seam in the back. + +.. figure:: 0304-sewing_front_closure.jpg + :align: center + +Sew a 2 cm × 2 cm square at the bottom of the webbing, plus diagonals +for strength. + +.. figure:: 0305-webbing_cover_front.jpg + :align: center + +Put the webbing cover so that it covers the square seam and the raw ends +of the webbing, and appliquestitch it in place. + +Structure +^^^^^^^^^ + +.. figure:: 0401-back_over_back_lining.jpg + :align: center + +Put the back over the back lining, wrong sides together, aligning it at +the bottom edge, centering it between the side edges so that there is 1 +cm of lining excess on each side, and making sure that at the top the +back is 2 cm longer than the lining. + +.. figure:: 0402-side_and_lining_over_back.jpg + :align: center + +Put one side lining on top of one side, aligned at the bottom and with 2 +cm of excess side compared to the lining. +Put the side on top of the back, outer / fabric sides together, aligning +the side of the side with that of the back outer. + +.. figure:: 0403-sewing_side_seam.jpg + :align: center + +Sew the side seam at 2 cm from the back lining edge (i.e. 1 cm from +every other edge). + +.. figure:: 0404-felling_side_seam.jpg + :align: center + +Press the seam open, then press the allowance of the back lining in +half, press the seam towards the side and fell. + +Repeat with the other side. + +.. figure:: 0405-sewing_front_side.jpg + :align: center + +Put the front on top of one side, right sides together and aligned at +the bottom and side edge, put the front lining on top of everything, +with right side on top, and aligned at the bottom and so that there is 1 +cm of excess of lining on the side. Sew at 2 cm from the edge. + +.. figure:: 0406-felling_front_side.jpg + :align: center + +Fell the seam. + +.. tip:: you can slide a metal ruler between the side and the side + lining to help you fell the seam without catching the outer fabric. + +.. figure:: 0407-aligning_other_front_side.jpg + :align: center + +Repeat for the other side of the front. + +.. figure:: 0410-attaching_bottom.jpg + :align: center + +With the body still inside out, put the outer base on the base lining, +wrong sides together, so that the outer is centered on the lining. +Starting from the corners put the base in the body, aligning the edges of +the body with the edge of the outer base and taking care to keep the +corners neat. Sew at 2 cm from the base lining edge. + +.. figure:: 0411-felling_base.jpg + :align: center + +Press the seam towards the sides and fell, trying to fold the corners +as neatly as you can. + +.. figure:: 0412-hemming_top_opening.jpg + :align: center + +Fold down the fabric at the top towards the lining, twice, forming a +hem, hemstitch it in place. + +Reinforcements +^^^^^^^^^^^^^^ + +Cut three rectangular pieces of reinforcement material, 3 cm wide and 2 +cm tall, fold them in half and sew them over the end of the straps. + +.. figure:: 0502-glued_bottom_reinforcement.jpg + :align: center + +Cut the bottom piece F out of reinforcement material, glue the side tabs +closed to form a parallelepipedal open on the top. + +.. figure:: 0503-sewing_bottom_reinforcement.jpg + :align: center + +Applique-stitch the reinforcement to the bottom of the backpack, making +sure to only catch the fabric and not the lining. + +.. tip:: depending on the material this reinforcement could be glued to + the backpack instead of being sewn, but this would make it harder to + change it later in case it was ruined from use. + +Variants +-------- + +Bound raw edges +^^^^^^^^^^^^^^^ + +Instead of flat-felling the raw edges, you can cut every piece with the +same sewing allowance of 1 cm, sew the pieces as instructed and then +bind the raw edges with bias or straight tape. + +Box corners +^^^^^^^^^^^ + +Instead of a separate bottom you can make the front and back pieces +longer and add a seam at the center of the bottom; this will make the +bottom of the pack a bit less structured, but can be significantly +easier to sew. + +To do so, instead of pieces A, A1, B and D1 cut the pieces Abc, A1bc, +Bbc and D1bd, and skip piece E and E1. + +Sew the sides of the backpack as instructed above, aligning the pieces +from the top, when the instructions + +Gallery +------- + +.. figure:: roll_top_backpack_back.jpg + :align: center + -- cgit v1.2.3
