When we were in Montreal this summer, we were standing in line at the Dairy Queen waiting to order our Blizzards. In front of us was a young man with a back pack that had a HUGE zipper. I came home and went looking for one. On etsy.com, I found http://gear.orgxiii.org/ which sells these giant zippers. Once I had one, I had to create something with it. Here is there result.
