The Belly Cast

Huichol mandalaThe belly cast is a wonderful way for the mother-to-be to create a beautiful record of her pregnancy and express her creative side.

Essentially, the mother’s belly is wrapped in a fast setting plaster-of-paris cast, which hardens into a permanent form.

It can be extended to include her arms, bosom, upper thighs, as much as the mother wants and remains comfortable through the process.

The belly cast can be created during a baby shower or blessing way as one of the fun activities.

Another advantage here is that you can have plenty of help, including someone to take pictures, as well extra hands when it comes time to clean up.

Total time from start to finish: approximately 30 minutes

The Materials


Kits are available online and from stores like BabiesRUs.

  • A plastic drop cloth to protect your furniture and floor.
  • 3-6  rolls of plaster strips – each one is 4 inches wide and 5 yards long. This is the same material that would be used for a broken arm.
  • Scissors
  • Rubber gloves
  • A basin of warm water
  • Lubricant – an alternative to petroleum jelly, a therapeutic salve
  • A paint brush and some gesso finishing paint


The Instructions

  • Cut the plaster strips into short pieces of multiple lengths, 2 to 18 inches in length
    Include pieces approximately 3 inches square for creating nipples and the belly button.
  • Allow mom to sit in a comfortable chair.
  • Coat Mom’s belly and breasts in a lubricant.
    This insures the cast comes off her body easily when the task is complete.
  • castDip each strip in the water. Do not soak or twist. Gently wipe free of drips.
  • Apply to the belly and body parts until there are about 3 layers of material.
  • Apply extra strips to the sides of the belly to strengthen or enhance the durability of the finished cast.
  • Work quickly. – After they become wet, the plaster strips dry and harden in as little as 2 minutes.
  • Remove the finished, hardened cast from the mother’s body.
    The cast will begin to separate from her body on its own when it is ready.
  • Use sandpaper or a sanding screen to make the surface smooth.
  • Allow the cast to cure approximately 1-3 days.
  • After the curing has taken place, coat the finished cast with a protective coating, such as spray varnish or lacquer


  • Insist mom take a bathroom break before getting started.
  • Be sure you have plenty of drop cloth to protect your furnishings. Newspaper works too.
  • If including a hand as part of the cast, spread the fingers apart to make them stand out.
  • Breast support during the casting: Wear a strapless bra.Cover it with saran wrap. Coat the saran wrap with lubricant.
  • Including the thighs: Do the thighs last. You will want the mother to stand up when applying strips to the thighs in order for the finished product to have the proper appearance.
  • If any areas of the cast appear thin, add addition strips to the inside of the form.
