My dad was a printer and over the years he would bring home (hoard) scrap paper and card stock. Having recently rediscovered a stack of Chipboard (that dense gray paper board on the back of legal pads) at least 3 feet thick, I have started using it as backing for some scratch building.
Folks always ask what’s inside the kits and I always say nothing but you can put in extra support. Well, I am enthusiastically recomending “Chipboard”. It cuts very cleanly and glues great. I’m building a mine for the new demo layout and the chipboard has been a great help in mocking up the basic forms to fit my landscape. I am then wraping the forms with our textures and getting very nice results.
I’ll post pix tomorrow.
