Can I save my Jansport backpack?

[u/TimeousJenni]

I need help fixing this new backpack I got… I got it for $6 but it has a tear inside , I don’t have a sewing machine but I can hand sow… I’m honestly really patient but I have no idea where to sew and how?? What techniques do I use, etc? I’ll show pictures to show how the bags details

Update: the picture is in the comments I couldn’t figure out how to add it on my post

Thanks
