After a discouraging few days lamenting the demise of my paper buildings...I buckled down and repaired and rebuilt them all and on top of that, built a nice church (also available free at GHQ) that takes only about an hour to construct. I was able to get all the wrecked buildings back into shape and despite a few bent spots they don't look too bad. One of them had a hole torn in the roof which I just left and painted some fire damage and it looks pretty convincing. Adding some bits of clump foliage around the bases also makes a huge difference (especially with paper houses since it encourages your eye to perceive the flat surfaces as more three dimensional and less "papery")
So now I have experienced the full ups and downs of paper terrain...andhopefully I can keep that little monster away from my stuff till she gets a bit older!
