How to make schoolbags by hand?

After studying fabric technology for a while, I wanted to show my achievements and set my goal on my son's schoolbag, so I borrowed some tutorials from the Internet and started my own creative journey. Although it was the first time to make a schoolbag, I didn't expect it to be successful. I felt that the effect was ok, so I made another one according to my idea. This time, I wrote a tutorial and shared it with all the mothers here. When making this schoolbag, when using the hidden seam method, we should pay attention to the fact that the stitch can't be too big and the zipper surface can't have a long needle and thread, otherwise the zipper will be difficult to pull!
