A variety of fabrics are used for sewing comfortable bake bags, but the manufacturing method is approximately the same for different types.

Instructions
Step 1
Transfer the pattern to the paper. Increase it if necessary. Backpack designs vary. A popular pattern of a sports backpack, consisting of a square bottom, four rectangles - sidewalls, a square with rounded corners of the upper flap. There are usually additional patch pockets on the backpack, there can be from one to five or even eight. The top of the pocket is closed with a flap with a zipper or buttons. The pattern may be simpler, consisting of one long strip equal to twice the height of the backpack and the width of the bottom, two rectangles-sidewalls and a top flap.
Step 2
Trace the details with the base fabric. Using aviazenta, calendered nylon and parachute silk, it is best to draw with a regular ballpoint pen. For all cuts, add allowances of at least 1.5 cm. The upper allowances should be at least 5 cm. Such a large increase is necessary, since you will have to sew with a linen or denim seam.
Step 3
Cut out the pieces of the backpack. It is most convenient to do this with a soldering iron or a device for burning out along a metal ruler. Scissors are not suitable in this case, the fabric will be very shaggy. Cut out the straps and belt from parachute lines, since now they can be bought at a regular sewing store. A corsage tape 5-7 cm wide is also suitable. If necessary, you can make a belt and a transverse strap from the same materials, which will be sewn at chest level.
Step 4
Mark the places for the pockets. It is better to sew on all the overhead details before you start assembling the backpack. For blanks for pockets, it is better to make a pattern from thick cardboard. The part should be slightly larger than the space allotted for it, since the pockets need spacious ones. Place the fabric on the mold, fold the seam allowances and iron them very carefully. Pockets do not need to be double seamed.
Step 5
Cut out 2 pieces for each valve. You can reinforce them with adhesive interlining. Fold the blanks together with the right sides and sew, leaving the edge unsealed, which will be sewn to the backpack. Align, align, overlock, and iron to the wrong side of the open edge seams. Baste the pocket and flap to the desired part of the backpack. If the flap closes with a zipper, then the order will be slightly different: first, iron the flap and pocket allowances, then sew in the zipper, and then baste and stitch both parts to the backpack.
Step 6
Baste and stitch the straps to the part of the backpack that will be adjacent to the back. It is better to sew them diagonally, crosswise, securing the corners and the point of intersection with leather or calender overlays. Like all the details of the backpack, sew on the straps with nylon threads.
Step 7
Baste the flap edge to the top edge of the webbing. If the flap is to be zipped, it must also be sewn on before assembling the backpack. But you can make a clasp on both metal buttons and buckles. On some backpacks, the flap is fastened with a zipper and buckles. In the latter case, the parachute lines cover the entire backpack - they are sewn to the flap, under the straps, to the bottom and to about half of the part on which the central pocket is located. The lines must be symmetrical. The free ends are 30-50 cm long.
Step 8
After all the overhead parts are sewn on, you can start assembling the backpack. The order can be any, but a double seam is required. For example, you can apply the following. Align the cuts of the parts so that one allowance is 1 cm longer than the other. Sew a seam. Fold in the free edge of the long seam allowance and sew a second line 0.2 cm from the fold. Other variants of seams are also possible.
Step 9
Fold up the top edge of the backpack and hem. Place the eyelets. An additional camera can be sewn to the bottom edge of the binder. It is a tube made of nylon or silk. Its height can be any. Hem the top edge. Insert two cords - into the drawstring of the camera and through the eyelets. You just have to sew the strands to the straps.
