Ok so in trying to keep this obsession thrifty to keep a happy wife, i came across 30x36 in sheets of coro plastic at the local big box hardware store. I said to my self "huh, thats the stuff that web site sells." (Yes i said it out loud!) Lol... so i pick it up got home and started measuring and cutting. These are gonna be 15" tall by 8" wide. I am going to go to the dollar store and pick up some cheap square flower pots for these to "sit on " to make them appear a little taller. Plan is to use the new lynx expresses i picked up in the coop (thanks kurt!) To use 1 color per channel. I will have 2 colors in each tree (blue and white). I can make 4 trees per sheet which was $7. Which makes that cost $1.75 plus $1 for the flower pot = $2.75 per tree (plus the feel good feeling of coarse!) Lol...
