How to make a papier mache belly cast

Updated July 20, 2017

Whether for a pregnancy or some other reason, belly casts can be used to preserve a particular moment in time. Belly casts are often achieved with the use of plaster and other casting materials, but you can also create a belly cast through the art of papier mache. With flour, water and some newspapers, you can create a belly cast for any occasion.

Rip the newspaper into strips. Mix 136 g (1 cup) of flour and 118 ml (1/2 cup) of water until you achieve the consistency of pancake mix. If the mixture is too thick or too thin, add flour or water in small amounts.

Dip each strip of newspaper into the mixture. As you pull each strip out of the mixture remove any excess mixture by running the strip through your index and middle finger. Place each strip of paper on the subject's belly, ensuring that you overlap the strips and cover the entire surface area. You do not need to put any preparatory ointment on the belly when using papier mache.

Allow the paper to set and dry on the subject. You can expedite the drying process by using a hair dryer set on medium heat. When you see the outside of the cast drying and hardening, try gently pulling off the cast from the subject. It may still be wet inside but you can gently lay it down to finish drying. If the cast doesn't pull away from the subject, allow it to continue to dry and try again later. When the cast is dry and off of the subject you can choose to paint it and add a coat of craft water base sealer to protect it from mould and add a glossy coat.


Wait until the mache mould is completely dry before attempting to paint it. You can put plastic bags inside of the mould to avoid a collapsing mould.
