Dead Alien - Halloween prop

Step 7 Paper mache and intestine paint

I started doing some paper mache, and while it was drying I sprayed the interior of the torso with red spray paint. Don't worry if it's too bright, we'll add some depth to it later. Leave some of the ribs exposed.
If your prop might be exposed to weather, you may want to toughen up you paper mache by adding white glue or latex paint. Make sure that you coat the fibers completely so that when it dries the mist/fog/rain/snow won't be able to get through.
Build the face of the alien using finely-pulped paper, or some other substructure such as packing tape. If you have a cheap pair of sunglasses with the appropriate shape, use them for the eyes by building the mache over the edges, sealing them in place. You may also want to leave flaps of 'skin" around the open wounds, whether they are on the face, body or appendages.
Add several layers of paper mache building them up and letting them dry. This step took a few days as the weather was already cooler and my workshop wasn't heated. You may also have to do one side at a time, unless you can find a way to hang your alien and let him dry.
