Plan C

I wasn't getting the look I wanted through any of my original plans, so I knew I needed to sculpt exactly what I wanted.  I filled the cage with polymer clay and sculpted in the stress lines.

 I then ran a heat gun over the surface of the clay to secure the details.

Then I attached a pour spout to the design and poured a silicone mold.  That all went fairly smoothly.  I then cut the clay out of the cage and placed the empty cage back in the mold.  Now I need to find a silicone that I can inject into this mold that won't fuse to the mold walls.  If I conquer this hurdle the project might still be successful!
