Run your thread across beeswax to apply a thin coating of wax to the thread. This will reduce tangles in the thread and make it go through the leather easier.

When using a chisel, rub the thongs on the beeswax to make the tool cut easier and pull out easier.

After using an edge beveler, rub a coat of beeswax on the edge and rub it into the leather using an Edge Slicker. It will give you a very professional looking and feeling glossy edge.
