I am in the process of re-building (yes, again.....but this time it's going to be the greatest yet) my "O" layout. Over the years, I have just painted the Homasote, covered the board with paper-backed grass, used an indoor-outdoor grass carpet and even spread the grain stuff over glue (messy). The plans are for a small 8' x 8' layout. This time, "$" and easy maintenance will be a priority. There are no current plans for fancy mountains etc. More or less, simple flat.
From your experience, what have you found to be the most economical and care-free covering to use? As always, thanks.
