This is called the Take Note Zippered Pouch (Crafted by Leanne pattern). It is a free pattern if you join Leanne's Facebook Group (pdf is in the files). You can find her other pdf patterns for sale in her Etsy Shop.
Leanne has a different way of sewing this zippered pouch and it yields great looking results. The only thing I am not thrilled with is that the zipper tape inside the bag shows and is not sewn into the fabric. But from the outside the bag looks great.
