Do you got something to replace those evil metal claws of doom? I know the security on State Street has laxed a bit this year, but there is still no way they are letting you in with those.

We have 15 days till Halloween, that is cutting it close, but I am sure I could make them for you in time. However it would be faster if you made them, because you do not have to worry about shipping them, and you can also be sure that they will fit properly.
1: Make an aluminum foil molds of your faces. Use enough foil to make it thick enough that they will hold their shape under light pressure, since you will be putting paper mache over them. Figure out where the eyes will have to go and work around that. You may have to adjust the masks a bit to make that work. Always remember, you are not going for a perfect representation of the movie, just something that looks right, and functions well.
2: Reinforce the foil with a light layer of mache (I use Cellucaly, it is far superior to an ordinary water/flour mix, and quite inexpensive) so it will be strong and wont change shape.
3: When that drys, build up the shape of the masks with newspaper. This will take some artistic talent that I cannot guide you through, either you got it or you don't
4:layer celluclay over the newspaper to get the final shapes, you may have to do several layers, so you will have to wait for it to dry in between layers. Putting the masks in the oven on low heat helps dry them faster.
5: paint the masks, and you may want to put a layer of black fleece of felt on the inside for comfort.
That's the best advice I can give. Hope it helped.
If you REALLY would rather I did it, I can help you but you have to pay for shipping and materials.
