First of all, there's two tutorials here. I wasn't satisfied with the first pair, so I made a new one - they still aren't perfect, so I'm making yet a new set, to make them more ram-like.
Though, these tutorials might be useful to those who want to make larger horns - the progress can easily be fitted to the kind of horns you want to make!
I find ram horns quite difficult to make, as the shape easily bends..
The first set is more time consuming than the second set.
I won't show how I got them to sit on my head, as the method I used is retarded and requires two people to get it on, haha.
But let's get started!
For the first set, you'll be using:
Hard wire // Paper form
Plaster // Polyfilla
For the second set, you'll be using:
Pipe cleaners // wire
NOTE! Here would be a good place to coat them with papier-mache, but I was too lazy to do it - papier-mache let's the Polyfilla bind easier.
Here you can also see the difference in the two pairs I made; the first pair ended up being too large, and bend out of shape.
I hope this was useful! If you have any questions about the process, don't hesitate to ask :D
