Logic: Well, if you go to a decent leather supplier you can get pretreated hides and thonging in a range of colours and thicknesses without needing to do any of the messy skinning and prepping yourself. Working the leather itself, once it is treated, is actually quite easy. You just need a sharp knife, some other tools (an awl, a leather hole punch, leatherworking needle etc) and a lot of patience. You can get proper leather working tools, usually from the same shop you get the hides from, along with any rivets or glue that will stick leather.

Once you have the right tools, most of the actual work is easy.
