1. Cut the fabric according to the desired size of the bag
2. Sew the two (or any more) parts together, avoiding the longitudinal sides
3. Cut 2 small rectangles from the leather imitation, fold them together, sew together on the left and then turn.Insert the two pieces as later loops and fix them
4. Sew the two side edges as well as the bottom edge of the bag, leaving the right and left at the top edge about 5cm open
5. fold over the fabric upper edges and sew together so that approx. 2 cm wide tunnels are created for the straps
6. for a bag you need a good 4m tape, split it in the middle and as can be seen in the picture through the tunnels (the simplest way is with a large safety pin)
7. Pull the straps through the loops and tighten them. DONE.
