First, draw a general teardrop shape on the sheet of aluminum. 

You can cut through with just regular scissors. 

Take the earring and lay it against a cardboard surface. Use a sewing needle to poke a hole near the top. Since it’s on cardboard, you won’t end up puncturing your table. Also, because it’s laying down, the aluminum won’t bend at the impact verses holding it in your hand.

Take wire (mine was just electrical wire) and cut it with scissors about 4 inches long. 

Thread the earring, leaving room in front.

Twist the space into a small loop. 

Twist 2 to 3 times until the loop is facing flat, the same direction as the earring.

Cross the wire to the back and twist the two ends tightly together.

Clip the ends shorter with scissors. Open up the loop of the already made French loops available at craft stores and attach the wire loop. Squeeze the loop back together. Here is the finished product. Enjoy your homemade, recycled earrings. 

Just a note: You might want to trim the very top part that is pointy to avoid cutting your ear lobe.
