What advice would you give someone starting this project? Choose your leather rather thinner than thicker. Sewing over 4 thicknesses of leather can be too much for a little household sewing machine. The bag is rather small in its dimensions (30 x 25 cms or 12 x 10 in), so I made a few modifications: The handle tabs did not go on the panel seams, but next to them. And the back side of the bag is just plain (no front pocket). This little bag holds a lot, even my water bottle!
