I hope you have as much fun making this project as I did.
The difficulty level of this bag is about a 5/10. You need to be comfortable working with thicker fabrics. It also requires a good amount of pressing, and precision is needed for the top stitching, binding, and zipper. That said, it is an unlined bag without interfacing, which makes cutting and prep work a breeze!
