Even More Stone Walls

I seem to be obsessed with making walls. This is the latest of my wall making. I built a form out of thin cardstock. The form consisted of a strip of the cardstock of the height I wanted the wall to be glued onto another strip of cardstock that acted as a base. I then squished a ribbon of polymer clay onto one side, used a stamping tool that I made also out of polymer clay to make rock impressions, then baked it. I then did the other side the same way. The result is wall #2 in the picture below. I still need to give it a wash, which will make the impressions of stone stand out more.

1) made directly from model railroad ballast, 2) made from polymer clay, 3) made from mold of RR ballast

I showed off wall 1 in a previous post. Not to rehash the pro's and con's of it, but frankly it looks too much like the home of a caddisfly larva:

Maybe I should have caddisfly larvae make my walls? They seem to know what they are doing.

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.
