pouch style cross body bag (Las Palmas Pk, Snvle)

hi, looking for a pouch style bag that's made of natural fibers or fabrics. one that's deeper than it is wider. I can add zipper across top opening, and a crossbody strap if necessary. also looking for some heavier, stronger fabrics like upholstery fabric to make one. pic is an example. I can use fabric that's lighter weight and would desire lighter color. thank you.
