Materials: cotton cloth, scissors, needle and thread, sewing machine, fountain pen, ruler, zipper.

1. Make the back of the bag first: cut two pieces of cloth with the same size, the size is 40cm long and 26cm wide. Place the front faces of two pieces of cloth opposite to each other, and sew the upper, left and right edges, with the front faces facing outwards after sewing.

2、? Making the front piece of the bag: You can choose the same cloth, sew two pieces of cloth together, and make the front piece in the same way as the back piece. You can also choose different fabrics, choose a thicker fabric with pocket decoration, because this cloth is thick enough, one piece is enough. The width is still 26 cm, and the length is half of the back piece, that is, 20 cm.

3. Put the finished front piece on the back piece, and then put the bottom pieces together. Because there are burrs at the bottom, you should fold the burrs in (as shown in the figure) and sew them from the outside, and then sew the two ends together. In this way, the shape of the bag is good.

4. Sewing zipper: Find an old zipper (if you like to do manual work, you should pay attention to the accumulation of some beautiful decorations and buttons on the clothes, and the zipper used by hand) and sew it at the entrance of the bag, as shown in the figure below:

5. Decoration: Turn down the lid of the bag to decorate it. You can choose decorations that you don't use at home.

6、? Sewing bag strap: The strap of diagonal bag is longer. I saved the rope from a dress, and now it can be used as a strap for my bag. Sew both ends of the rope on the left and right sides of the bag, so that the bag is finished.
