The cast I made using railroad ballast really looked nice ( Wall 3) and is what I was going after, but the two sides of the wall didn't fit well. I think I might try making more of the wall 2 method. It is less tedious than making wall 1, and I don't use up bottles of superglue gel, which have become pricey. The cardstock form has the advantage of keeping the height of the wall a little more consistent and doesn't melt in the oven.
