1. Prepare a form for top layer elements of a backpack according to the dimensions given in the picture above; cut them out of a material with a 1cm seam allowance around.


2. Prepare a form for elements of a lining according to the dimensions given in the picture above (it is shorter than a top layer); cut them out of a material with a 1cm seam allowance around.


3. Prepare a form for leather elements according to the picture above: 2 loops of 2cm x 8cm / 2 pads under press studs of 3cm x 3cm / 2 loops for handles of 4cm x 14cm / a fastening in a shape of the letter "T" of 25cm x 4cm + 43cm x 3cm.


4. Arrange leather elements on a material.

Arrange leather elements on a top layer; you can not baste a leather so in order to facilitate sewing, glue elements temporarily.

Install a needle for sewing a leather; sew leather elements; do stitching on loops in a shape of a rectangle but only along shorter edges – you must leave unsewn space of 4cm in the middle; sew square pads around; sew a fastening in a shape of the letter "T" only on a horizontal strip; do rectangular stitching by shorter edges and in the middle – leave unsewn spaces under which you will insert handles made of a line (see the following pictures and the final one); other two leather elements fold in half and glue shorter edges so as to form loops.

In the picture below, pink pens are inserted under unsewn portions of a leather; now arrange a side element so that a shorter edge covers the 1 cm wide allowance in the center of a main element; sew 1cm away from an edge; do the same with the other side element, on the opposite side; glue loops made of a leather on the side of a main element where a fastening in a shape of the letter "T" is sewn; place loops approximately 3cm away from lateral elements with a loop facing toward inside of a main element

Fold a form so that a long edge of a side element covers with a long edge of a main element; if they differ in length, you will level them later; sew together these two edges – when sewing a leather loops, use a needle for a leather; when a presser foot leaves a loop, make a fastening and replace a needle with a one for jeans; do the same on the remaining 3 edges – as a result you will have a shape of a backpack; after sewing, level a length of elements on the top edge of a backpack.

Press edges of a bottom and sides with an iron and do reinforcing stitching on edges at a right side; hence a backpack has a distinct shape.
Caution! Do not sew the last 6cm from the top of a backpack on edges of sides – you will do a stitching there after sewing up a lining; remember to change a needle before setting about sewing a leather.

Change a needle for a universal one and similarly to a top, sew all elements of a lining; leave an unsewn fragment 15cm long a one of side edges.

Turn up a lining on a right side, and a top of a backpack on a left side; insert a lining into a backpack; fasten edges of an opening; install a needle for jeans and sew around edges of a lining with a top.

Pull a lining out of a backpack; turn the back pact to the right side through an opening in a side seam of a lining; sew up the slit in the lining; insert a lining inside the backpack; press an upper edge of a backpack with an iron so as to turn it up inwardly by about 2cm (a lining is shorter); do stitching on a line between a lining and jeans.

Now you can complete reinforcement of side edges at a mouth of a backpack; within these seams, you will also sew edges of a lining so as to prevent it from turning up.

Now it is time to stud press studs – in a packet of press studs, there are also tenons and pads for studding and an instruction manual; you must hammer press studs; if you are doing it for the first time, hammer only two studs to test on a piece of a material.
Start with executing a small cut in a material where you want to hammer a press stud; push a neck of a stud to a hole, place it on a pad, put the other part of a snap on a neck on the other side of a material; arrange tenon on a neck and flatten a neck by hitting a tenon with a hammer – see an instruction manual on a packet of press studs; remember that a fastening consists of two parts of press studs of different shapes.

Fasten a top part with a lining by means of press studs; pin a lining inside a backpack so that it coincides with a shape of a top; hammer bottom parts of press studs on two square leather pads; now hammer three press studs on a top edge to fasten a backpack; in order to mark position of upper parts of press studs on the "T"-shaped element, fold an upper part of a backpack along a horizontal edge of a "T" element; mark where to hammer press studs on a vertical strip so that they match those hammered on squares (see a final picture).

Finally, insert a line into the loop on the side and under the unsewn part of a "T" element; tie ends of the line and firmly twist a thread around them to prevent a line from fraying. The backpack is ready!

Fasten a lid in a conventional way – using a lower press stud; you can also roll a lid up and fasten a strip to a press stud higher located above.
