The first thing you will want to do is cut down your leather sheet small enough to fit in your die cutting machine.
Sandwich your die sharp side onto your leather in between your pads. It may take some experimenting to find the perfect "sandwich" recipe for your die cut, because all die cuts vary in thickness.
Roll your leather through the machine
Take your die cut off your leather. Your die should have cut through the leather leaving you with a shape. Peel that shape away from the rest of the leather.
Hole punch a hole at the top (if the die cut doesnt already have one)
Using your Jump Ring Opener, open the jump ring and loop it through the hole, along with an earring hook. Close the jump ring.
And that's it! Repeat the steps for the other earring.
Spice them up by adding additional layers and charms!
