You need to coat the clay with vaseline or some other grease-based substance
to prevent the paper from sticking to the clay. Even so, there is still a
residue of both the clay and the grease on the back of the cast paper.

Create a sheet of paper as you normally would and then couch it over the
clay. You can overlap more than one piece of paper if your object is larger
than your screen. Make it thicker than you normally would so that you can
mold it with your fingers over the contours of the object (whether clay or
some other substance). You can use a layer of cheesecloth or tarletin over
the pulp to reinforce it if the clay is extremely dimensional.

You will need to clean the clay again if you want to use it for clay
projects. I normally wipe it off as best I can and then immerse in a soapy
bucket of warm water and wipe dry. Throw the sludge water outside instead of
down the drain.

You can bypass this by using plasticene instead of clay, which doesn't need
any lubricant.
