It's not difficult and you could adapt it to suit a number of different types of headgear. This one would work well for a Predator, Giger or one of the ones here:
I have nothing to do with that site but there are loads of ideas on the net.
Step 1: Find a Base
Hot melt glue
Liquid Latex (see my earlier 'ible for safety warnings)
Acrylic artists paints and inks
Aluminium car repair mesh
If I were to do this one again, I would certainly use a bald cap. The method used here turned out to be far too bulky at the front, although it was comfortable and quick to put on and off.
If using a bald cap you need to buy one of the heavyweight types or make your own using at least 20 layers on the upper dome. You also need to allow extra time to fit it.
Here I have use a shop dummy for the stand, but I would use a glass head in future since the head of the dummy was a bit small.
For the base I have used a baseball cap, the brim has been trimmed down to an inch wide, the brace has been cut off the back and a felt liner has been added. The cap is on backwards. The dummy head has been covered in food wrap to protect it.
Step 2: Start Adding the Bits
You could add feathers, or ropes, or pre-formed latex parts, almost anything. Just bear in mind the weight for your user!
I've added an aluminium wire mesh for support here. Another mistake I would leave out of using a bald cap.
Step 3: Add More Stuff
Step 4: Strengthen It Up
The front has had a very thin layer of cotton wool and liquid latex added to start the build up at the front.
Step 5: Tissue Paper Shaping
Step 6: Keep Building Up
Here i am working on the sideburns.
The big bit of grey felt is to stop the latex getting on the sides of the dummy and to try and compensate for the small head of this mannequin. - Use a bald cap next time eh?
Step 7: Blend Out the Ends of the Lox
You can clearly see where I have marked the positions of the blends with a felt pen.
The straw colour is the colour that natural latex goes when it's cured.
Step 8: Finish the Blends
Step 9: Blending and Feathering
Step 10: Adding Feathered Edges
I have added extensions to two of the blends.
This is a case in point of more is too much. You have to force yourself to stop adding shit to your creation. I don't know why I added these two extensions, but I feel that the original configuration was actually better ....... too late now.
Step 11: Start Adding Colour
Build up the colour in layer to add depth and suspend disbelief.
Take plenty of time with the colouring, it will make or break the creation.
Step 12: Finishing Up
