Step 1: What you need
Little hacksaw, scissors, awl, may be a revolver rod, felt tip pen.
Your materials even simpler:
two empty plastic detergent (dish wash) bottles
One big detergent bootle (clothes)
And a string of christmas lights (led) from last year, to be reused in another creative way next year. Mine is 40 leds long
Step 2: The head
I started with my hacksaw at the neck of the bottle and cut the rest with a pair of scissors
Step 3: Antlers
Step 4: Connect antlers to head
Step 5: The body
Step 6: Connect body and head
I made a bigger hole in head and body part wich cannot be seen when head and body are attached together. This allows me to pull a section of the Christmas-light string through the body into the head.
