Haha, you came across that old thing?
Damn, such a long time since I did those, and I never got them finished (I kept getting more important stuff in the way). :b
You made it out of toilet paper? Sounds very interesting, to say the least.
- Overall I'd say that a mixture of flour and water (for a cheap mix), or some wallpaper paste mixed with water (better adhesive, I guess?), mixed with a lot of newspaper would be the fastest, together with a balloon, in order to get the right shape, would be the fastest I can think of.
When you've reached those 4-5 layers, you can pop the balloon, and using some tape to keep the shape, you can apply layers and eventually use a heat gun to be able to apply several layers in a very short period of time.
Other than that, I have no idea for a faster version.
I've done a little bit of the scarred version, but it was my first time with fake skin, and also with makeup (although a friend applied that for me) - the fake skin I cut up and put "together" was terrible though, so only some bad pictures ^-^
You can check
for some pictures we did, if you're interested :b
