Well, not really the surface of the moon but to me it looks like it might be related to the moon. My foam armature of a horse. A big horse. So, as things are moving forward with the square chunks of green foam and a few blue ones (leftovers in my small studio behind my house where most of my molds are stored right now), I’ve moved to the canned spray foam you would buy at Lowe’s or the local hardware store. I could use a more professional grade foam from one of my art supply places, but it’s got smelly issues and I really shouldn’t be using it in a closed space without really good respirators and big windows opened wide. So, I use the do-it-yourself cans and let it set up then apply some more, while I go do something else. Or, there are big blocks of polyurethane foam you (or me) can carve to the shape of an animal or human or whatever. I don’t like doing this reductive method, because, well I’m a modeler, I apply clay, carve it back a bit, but mostly add clay to an armature. I don’t do stone carving and I haven’t tried carving a block of wood, yet.
I’ll use the chunks of foam again when putting his neck together. Then I’ll use foam to tune it to a more organic shape. Big to little, opposite in oil painting which is fat over thin. Fat is oily oil paint, thin is oil paint thinned with turpentine for the underpainting. So big chunks or broad expanses of foam from an 4′ by 8′ sheet of 2″ construction foam, then itty bitty pieces of spray foam that look like a moonscape until I grind it smooth with my manly man grinder sander.
