Hello! We are going to have sew much fun making Sew Together bags together! I like using these zippers by the yard to make mine for the outside zipper. We will order some of these for you to use at the sew along if you respond to this survey by October 15 and indicate which color of zipper you'd like! (We've limited the options to limit the number of colors we need to order and to consolidate a bit.) To see the zippers and colors, please visit this website: https://www.pamdamour.com/product/home-dec-zippers-by-the-yard-3-yard-package/ Then, come back and let us know which color you'd like! Thank you!
