I would like to make a rotating tunnel for the entrance of my party. Not sure how to go about it...I do have two 13' pallets from our addition we built last yr. Thinking that I could affix them to a steel frame with supports underneath for stability. My problem is what to use as the tunnel. And then what to paint on the inside of it and just how in general to make it all!! I'm going to make a huge clown face with the mouth as the entrance in front of it all since my theme is psycho circus!! Don't know if we can pull this off but we figured we'd give it a try anyway. Any help would be AWESOME !! THANKS !!
