I remember reading a tutorial thread (I think it was on here) about how to use paper towels and Hydrocal for scenery. I can't seem to find it now. Looking through the Walthers catalog last night for something else, I see WS offers a pre-made cloth you just soak in water and drape over you base. Anyone care to critique these methods? I like the WS idea for ease, cost is of course higher but one pack would probably do most of my small layout and might get me further along more quickly.
