hey guys, just back from a train show. there wasthis guy with a very nice layout and he scratchbuilt all his models.HE showed me the brick sheets he used and it was really thin, like a sheet of paper, and it still had relief. THe material was plasticy and was bendy like a sheet of paper. my question is, where can i find this! I am currently using the walthers brick sheet and it's way too thick and i have trouble cutting into it and making precise holes for the windows and doors.
