cardboard, acrylic paint, gravel, a old towel, glue, tongue depressors, popsickle sticks and some old wire fencing

I had the old collection and the new one came out so I thought I'd make them a playmat for the base. Since these pics I have added a dock and a larger heliport and now I'm working on a Springfield warehouse for the Cobras. This playmat took me approximately a week to make. I'm looking to see if I can make more for my friends who collect as well. Its pretty huge with all the add-ons but it is soooo cool.
