Herschel Duffle Upcycle | My gym bag ripped, but I loved the color of it and decided to seam rip out the strap, zipper and stuff sack pocket. I had started commuting regularly to a pottery studio in Brooklyn and needed a bag that I could get a little dirty. I introduced new canvas, waxed with beeswax to make it waterproof, and made a bag that fit my every need.
