this is a slightly complicated build yes but if you set aside some time it is accomplishable. for this instructable it is important to note that the materials are not cheap and the method requires sculpting ability and patience. I know there are plenty of you out there that can achieve these results so if its something that interests you GO FOR IT!

make sure you sketch out a few ideas of what you want to make before you start or at least have a lot of reference pictures to go off of.

Step 1: Materials

for this instructable you will need the following:

1. clay
2. styrofoam
3. amber shellac
4. apoxie sculpt
5. Silicone
6. liquid latex
7. flex foam
8. paint
9. faux fur
10. sculpting tools

Step 2: Getting Started.

so you have to start with a base

in this case I used Styrofoam

I used a very dense floral foam and then shaped it and covered it in a few coats of amber shellac to give it extra strength
you can use anything as an understructure really including another sculpture but it really just matters on what will work best for whatever you want to make

once all the coats of shellac are dry you can start putting on a base of clay and start roughing out your design

Step 3: GET SCULPTING!

next its all up to you and your artistic ability

i used two plastic teeth molds that i made for an earlier project to assist in the sculpting of the teeth
i also used two plastic balls to stand in for the eyes

the claws and large fangs were all made out of apoxie sculpt.

once you are happy with your over all sculpture you can begin the moulding process

Step 4: Moulding

there are many ways to mould your sculptures and there are better choices depending on the final product

for my purposes i wanted to make it out of silicone to make both soft and rigid final products.
i used a fast cure silicone so that i could brush it on all over the sculpture and keep the overall mould thing and economical

once the silicone is cured you should make a sold jacket to keep its original shape i suggest using fibreglass if you can but plaster bandage also works but just make sure its strong enough to hold the shape of your sculpture but you must also be able to easily remove and put the silicone mould back in

once you have a solid jacket ready to keep its shape its time to remove the sculpture as you can see i just ripped mine right out.
now you can start your casting and ultimately your final detailing

Step 5: Casting

in this case i used liquid latex as a skin coat to capture the detail
i poured in a bucket of latex and slushed it around to accomplish this then poured the excess back into the bucket

after waiting a few hours for the latex to dry i mix up a few cups of flex foam and fill the entire sculpture after that is cured you can pull the whole thing out and get to painting and furring the creature

(I apologize for the lack of photos for this, i just did this portion quickly and didn't have time to take pics)

Step 6: Final Product

i cut forms of fur and stuck them on with a heavy duty adhesive formulated for latex

i painted the body and fur and added spines down its back by cutting some feathers and the end result speaks for itself

this creature looks great anywhere outdoors but to give it that creepy wild feeling indoors i made a stand out of styrofoam and sand and fake plants

hope you enjoy the chupacabra!
