Foam Factory Hot Wire Tools

I purchased a couple foam hot wire sculpting tools from the foam factory, and was pleased with them. They quickly melted through even blue foam.

I decided to make a Vauban style star fortress; here are some pictures of the progress so far.

After cutting the three layers and pinning them together, I primed with brush on chalk board paint hoping for a little texture. A little disappointing and it smelled poisonous.

I dry brushed with gray and brown. I don't know how to improve the dull look. I'm going to try spraying it with wood stain and dry brushing again.

Here's a 28mm Old Glory hand gunner for scale.
