My entry for the Holiday contest is Shotgun Shell Christmas Lights! The Shotgun Shell Christmas Light's were used on our Christmas Tree this year to go on with the theme of Shotgun Shells and Jingle bells. Please Vote, Share, and Favorite!
I didn't think to make an instructable till I was done, so most steps are already completed.

Step 1: Gather You Materials!

-Christmas lights "I didn't take a picture of the lights before making them"
-Pliers "Preferably Needle Nose"
-Shotgun shells (Used) 12 Gauge and 20 Gauge will work. Not sure on .410 Gauge.

Step 2: Begin Making the Lights!

Take your pliers and start to crimp the Shotgun Shell.
There are many different ways to do this, but I found pushing the end of the pliers into the shotgun shell worked best.

Step 3: Time to Finish of the Lights!

After pinching yourself, a couple of times, and muttering some, let's put some shotgun shells on Christmas lights!
Start by finding a hole in the crimp of the Shotgun Shell.
Once found, slowly wiggle the light in the hole.
Now repeat a couple hundred times depending on how many lights you have.

Step 4: Finished Shotgun Shell Christmas Lights!

Congratulations! After about a hours hard work, your Shotgun Shell Christmas Lights are completed!

"For Indoor use only unless you Silicon the shell shut at the crimp."
