F and I made an interesting order today. A friend asked us to make a backpack for her neighbor to carry two half gallon glass Mason jars of water. Her neighbor gets her water from a spring near her house every day and currently carries a bottle under each arm on her hike to and from the dpring. We designed it to safely cradle the two large full glass bottles and attached shoulder straps to make it easier for her to haul so much weight. Today's drawings show the features of the water bottle backpack.
