Just a quick pic of the nearly finished tower. I plan on doing a post on the process, but here's the result so far. I'm pretty happy with it. Behind it are the walls made for my castle project using Hirst Arts molds. Those are great, but they're very heavy and fragile compared to this result, may have to abandon that route...

I've also started a couple walls using the same process, they're about 1/3 the height, and about as wide as the tower is tall. They're also based on a cardboard "core" - more on those later!

The figures are 28mm Rackham figs, for scale.
