well if you have a old cork board laying around just take it out of the frame and use it it is the same size as road bed. i found 10 of them at the good will for about 2.00 for all . and they where about 24" x 30" so for a nscale layout their is a whole yard in about 2 of them . or you could use the thick card board from a frige, or stove box just glue it down and lay your track and if you wanted to you could use plaster over it to make little mounds of rocks. but you can just balast right on to the card board i did this on a old layout and it look great .
