Nets of a Cube

The net of a solid represents all of the connected faces of the solid. When you fold the net at its creases, you should be able to recreate the solid. For instance, in the figures below, the net shown to the left will create the cube to the right if you fold the net at each of the lines.

There are a variety of nets that can make a cube. Devise as many possible nets for a cube as you can.
