Well, this tutorial has been a long time coming! Hope you all enjoy! I tried to take lots of pictures, but if anything is unclear, just let me know! Things to know: This tutorial will be for a 12" zipper, but I will give you some dimensions and tips at the end to make other sizes. This tutorial is specifically designed for metal zippers. You CAN make the bag with a nylon zipper and it will work just fine. Since you can sew over nylon zippers, the zipper can actually be longer than required…
