A while ago a teacher friend of mine asked me to make a severed pigs head for a school production of The Lord of the flies. My instructions were to be as gorey as possible, but to pretty much do what I wanted!
I decided to use a method I learned at uni, as it would make a strong but light head that could be flung around by a bunch of teenage without getting damaged or damaging any of them. (Health and safety!)
The first step is to make a rough sculpt of the shape you are making. If you were making a detailed, complicated shape, sculpting it out of clay would get the best results, but as a pigs head is a fairly basic shape, I made it from scrunched up paper held together with Sellotape.
Next I covered the whole thing in clingfilm, this lets you take a pattern of the shape off.
Next you will need to mark the pattern so that you know which piece goes where; putting a few labelled dashes across the edges of each pattern piece will let you match up each piece really accurately.
To get a piggy colour and to add some texture and cover the joins, I covered the whole thing with strips of fabric, pasting them on with liquid latex mixed with acrylic paint.
Now for the 'decoration'! I mixed up some really bright red acrylic paint and latex and painted and dripped on some horrific wounds!!
