I'd like to see you improve upon it.
Step 1: Step One
You'll also need a welder (I used flux core wire) and some knowledge on how to use it.
Step 2: Step Two
Depending on how many you choose (I used seven) determines how the set up is.
I added the seventh as the "trunk" after the tree was finished.
Step 3: Step Three
I chose three larger shoes for this step.
Step 4: Step Four
Step 5: Last One
I'll finish mine up after making a star out of horseshoe nails.
That'll be posted at a later day.
