One of the major industries on my planned layout will (hopefully) be a foundry. Since none of the commercial kits suit me I'll probably end up scratch building. Since I'm frugal (OK, cheap) and I've seen some great work one in cardboard here on the Gauge, I thought I'd probably build in cardboard, but I want it to look like brick. What's out there that I could attach to the cardboard to look like brick? The best solution for me would be bricks I could print on my printer, make as much as I want for the cost of paper and ink. Any suggestions? Thanks in advance!
