I’ve been making quite a few of these medium sized heads recently, I think it’s because they’re a nice size to work on and once they’re sited in someone’s garden they still have presence. I’ve tried different materials in the mould and it’s surprising how different the finished heads look. The first few I tried, I left to go rusty but I’ve galvanised a few too. The most tricky one was the one with horizontal strips of flat bar because it took a lot more steel than I thought to make it stand up and not act like a slinky and start bending over. I never know how they’ll turn out until they come out of the mould, which is part of the fun of making them.
