I was travelling overseas and I had this idea of a messenger bag to carry around my water-bottle, snacks, scarf and gloves etc. Previously I had carried a backpack on such trips, however i had been made to put it in locker rooms and it got in the way on trains. The messenger bag would look less touristy. I had some black waterproof canvas that I had bought for this kind of project and some webbing. I found a pattern on a Youtube video, so changed the measurements to suit me and sewed it up in an afternoon on an old Singer 201 with some nylon bonded thread. It turned out really well. The fastener on the front flap is not quite in the middle, however it is all black so hard to notice. I carried it around Japan for 2 weeks and it was perfect. Folded it up and stuck it in my main luggage to come home.
