Oh yeah, this is gonna be good.
Off to share.
Thanks! I like this time of year to build. I can work outside, let stuff dry, longer daylight hours. I can probably make it into something cool in a week.
I like how that looks. The "ribbing" in the foam works really well.
If I tried to replicate this using XPS board, it would cost more than $50 and take more than 2 weeks to build. This costs nothing, all I need to do is fill in the gap around/behind the bunker entrance. Probably just give it a couple coats of Modge Podge, paint it and done.
My second choice would be to build a mountainside, using cardboard, paper, plaster etc. But it wouldn't be modular, it would probably get damaged everytime I break it down and store it. This is the most logical solution.
