I’m using air dry clay to sculpt the boulders that populate the Warming Hut foundation. For the largest one I used a small tin and a plastic cup as a base, then coiled unevenly-rolled lengths of clay around it.
I made certain decisions about the type of rock I wanted to see, then used my hands, a small metal ruler and a ball point stylus to make like the earth, wind, water and all the other magics of geology.
This is my model rock for style and color.
Even though the clay’s just one day dry, I’ve put the first coat of acrylic glaze on. There are a lot of rocks to build and paint. Most of them will fit under the foundation, as if the posts have been drilled and set into them, so the painting part will be a wee bit tricksy. (That was part of my conundrum of when best to glue or not to glue the hut in place.)
The gaps between the boulders will be filled with beach gravel and tiny pebbles (from my prized collection), with some driftwood logs wedged in here and there, and small bits of greenery.
