I've decided to try making some small things with leather.
The first thing I made was a card case. There are two pockets and it folds in half.
The second thing I tried making was a cable tie. There was no sewing involved, and it was rather easy. I just had to use some hammer to put those rivets and snaps.
I find that sewing leather with an industrial sewing machine goes quite smoothly. (I don't really know how it is with a domestic sewing machine. Maybe it's easy, too.)
I tried to make a wavy kind of patterns for the pockets and added a snap to keep the case closed in a bag.
