Thirty One Fresh Market Thermal Tote Picnic Party Bag Pink Red Floral Collapses

This thing has barely been used, very minimal signs of wear on the very bottom. It completely collapses to almost flat. Well insulated thermal material. Vibrant floral color exterior and a solid sturdy bottom. Upon closer inspection, there is about a 2 inch area where the stitching has cleanly come off of the zipper attaching the fabric. Very easy fix I just don't know how to sew.
