Terribly sorry if this has come up recently (I searched before posting, I swear I did), but I am trying to put handles on a bag that I just made (my first attempt at making something more complicated than a wallet). I'm pretty satisfied with it (it's a sort of Gladstone/Doctor's bag), but now I'm getting worried about screwing it up. I had planned to cut a bar of leather, fold it in half, stitch most of it to itself, and then stitch the rest into the bag, as is pretty common with purses and the like. However, this bag is a good 16x10x12, and I mean for it to be able to carry my books and lunch and whatever else I need. In other words, I need it to carry what I would reasonably carry in a messenger bag or smallish backpack. Should I be worried about the strength/integrity of the bag and handles using this method? Should I use an intermediate metal ring or loop between the handles and the body of the bag? Should I use rivets as well as stitching to make it extra strong? My stitching seems awfully strong usually, but I've never made anything that would get quite this much abuse before and am concerned. Thanks all!
