putting up retaining walls again all the wood will be painted Black and thinking once I get a ground plane in just for safe measure I will put Styrofoam painted black on the ceiling to hide the wires and cut down on some of the light in the tunnel . u used up all the walls I made last night so I will be spending the rest of the night making more. I also finished a tunnel portal mold and pulled a portal out of it I only needed one. but you never know when you need more. also at the far end of the last picture I have a retaining wall made that is curved to fit there it's drying at the moment I just painted it .
