We chose to make a circle with vector graphics software, but you could also draw one with a compass.
Find the phosphor side of the EL panel-- it has a plastic overlay you should leave in place.Trace the circle onto the plastic overlay with marker near where the panel's wires connect.
Sometimes the edge of cut EL panel can give you a little electric shock when you touch it-- you can optionally seal the edge with clear nail polish or the craft glue you'll use in a later step. This will also help make the shoe mod more durable.
You can use the star tool in Illustrator-- while holding down the mouse button you can use the up and down arrow keys to change the number of points in the star, and also hold down the 'alt' key for a star with parallel lines.
Remove the vinyl's backing and stick the star to the phosphor side of the EL panel. Pay attention to the wire connector on your EL panel-- it should face up toward the top of the shoe when you stick the star.
Plug in your inverter and test that your EL panel lights up.
Carefully place the EL panel on the glue and pinch to the shoe for 1 minute for good adhesion before allowing to fully dry for 24 hours. You can use clothespins as tiny clamps.
