I will be touching on the steps of making a mask and a foam latex glove unfortunately there is abit of extra knowledge to learn to be able to use some of this stuff so if you wish to learn more look into it. there are online classes and tutorials that can show you the basic skills.
to start you will need a bust to sculpt with and a hand to sculpt the glove or gloves. doing this one bust of yourself is the best way but a generic bust or even mannequin bust can work just fine.
Step 1: Getting Started
i suggest you sketch out your designs before hand or at least have a lot of reference material readily available
I like to use medium chavant it seems the easiest to work with. the soft is also good but i prefer a harder clay
this stage can take awhile depending on your skill level
once you are happy with the sculpt its time to mould it.
Step 2: Moulding
make sure that you cover your clay in a good clear coat spray before you apply the ultra cal this makes it alot easier to clean out the clay later.
once the clay is out and the moulds are clean you can begin your casting in latex or foam latex when using foam latex it is also wise to reinforce the inside by laying some sort of stretchy mesh or pantyhose on the base
i only posted pics of the mask casting but its the same process for the hand
Step 3: Painting and Decorating
at this point its alot of artistic layering and painting to add dimension to your mask use an airbrush to darken the folds and add specle colouring for a texture look .
Step 4: Application
put together your costume as you like it and you are ready to go
(i also put in some crystal blue contacts to brighten those eyes)
and there you have it.
