Starting a curve fold for a packaging design

However it looks like a kind of chair, you are watching the back side of what I am starting to design. This shape will become a package for cycling shoes plus the package will be a hardpack backpack. So will be less trash plus extra function into the package. I am using the curve fold to become a more ergonomic shape for a backpack to follow the curveture of your back.

Will be made from plastic and also be playing around with fabrics for the first time, however I won't be sewing but looking into fabric gluing and see how that works.
