I wanted to enter a competition here in Johannesburg, South Africa where I stay. The competition was to design and make a prototype of a serviette holder. The inspiration was states as follows... "Dining and entertaining plays a significant role in people's lives. Whether it be formal ceremonial or celebratory occasions or impromptu, informal gatherings, table napkins and serviettes are always needed. Display an unusual and beautifully designed serviette holder and transform the ordinary into the extraordinary!"
The prototype was to simulate metal as the intended material for manufacture.
I wanted to enter, but with a humorous play on words at the centre of my design. The Porkupine would sit on a table, as roast pigs did in the past (sans the apple). The quills of the Porkupine would be made out of rolled up napkins/serviettes, similar to the quills you may have seen in the Porkupines cousin, the porcupine.
This instructable is an interesting set of steps showing how I got to the final form, as well as how I simulated the finish of cast alluminium, using corrugated cardboard, and automotive body filler.
It illustrates that corrugated cardboard can be used as an effective model-making and prototyping material.

Signing UpStep 1: Maquette made from clay
I roughly sketched the form of the Porkupine until I got to a form which I liked. I then began modeling the form out of a modelmakers putty which is a similar consistency to plasticine, allowing me to mould the form of the pig.
I made several maquettes before setting my mind on this one.
You can see the size of this to be approximately 50mm long (2 inches). I photographed the model from the front and top, and scaled up the images on the computer. I then printed these out, and began laminating many layers of corrugated cardboard.
I used double-fluted cardboard which was approximately 8mm thick. I glued layer upon layer to create a solid 'block' of cardboard about 15cm thick (6 inches).

What was the sanding sealer for MDF board that you used, could you just use more auto body filler instead?
