I don't always have pockets (or simply, large enough pockets) to carry small items when I go out. I saw a tutorial on a leather cross body bag that seemed fairly easy. I did not get leather but instead got marine vinyl which feels similar to leather. This is the bag I made. The fabric was not the kindest, but I made it sort of work. There are detachable straps on this bag. It is the perfect size for the few items I usually carry.
