DIY Plaster Ornaments: Step-by-Step Guide for Beautiful Décor

Can the texture of plaster ornaments be beaten? I honestly don’t know.

Plaster ornaments — two simple ways. I made these back in 2021 and photographed the process, but it was so close to the holidays that I never posted a tutorial. When I unpacked them a year later to hang on the tree, they felt a bit plain, so I spent an afternoon painting a few with colors I already had. The result felt painterly and playful — a cross between a paint palette and tiny abstract paintings.

Not sure which version I like better, but here’s how I made plaster ornaments in two ways.

Materials for Plaster Ornaments

You only need a few materials to make these ornaments:

  • paper-mâché or craft ornaments (as the base)
  • plaster or pre-mixed joint compound
  • small putty knife (optional)
  • paint and brushes (optional)

Note: You can mix your own plaster from Plaster of Paris and water if you prefer. That may be slightly cheaper, but for a fast, easy route I recommend using a ready-made joint compound or plaster from a home-improvement or craft store.

How to Make Plaster Ornaments

Technique 1: Apply compound to ornaments

Work one ornament at a time. Start by spreading the joint compound or plaster over the surface. I initially used a small putty knife, but quickly found it faster and easier to use my hands to press and shape the compound. If you choose this method, wear gloves — working with plaster by hand is messy. If you plan to use gloves, you can skip adding the putty knife to your supply list.

Technique 2: Let dry and add paint (optional)

Allow the plaster to dry completely (I left mine overnight). If you like the plain white, textured look, you can hang them as-is once dry. To add more personality, paint on colors and brushstrokes. I experimented with a few different stroke patterns while keeping a limited color palette so the set remained cohesive. Painting is a particularly fun step to include kids in.

If you want extra protection, seal the ornaments with a matte or satin sealer. I left mine unsealed for a fully matte, natural plaster appearance.

The finished plaster ornaments are tactile, colorful, and ready for the tree. They also work well as a holiday garland or as unique gift toppers.

More ideas and variations

Instead of starting with pre-made craft ornaments, try cutting shapes from cardboard and coating them with plaster or joint compound. That approach allows you to make custom silhouettes and results in a very unique, handmade look once textured and painted.

Quick Recipe: How to Make Plaster Ornaments

Equipment:

  • paper-mâché ornaments
  • plaster or joint compound
  • small putty knife (optional)
  • paint and paintbrush (optional)

Instructions:

  1. Add compound to ornaments. Apply joint compound to each ornament, using a putty knife or your hands. Hands are faster but messy — gloves are recommended if you don’t want plaster on your skin.
  2. Wait for it to dry and paint if desired. Let the plaster dry fully (overnight works well). Leave them plain or add painted brushstroke details in a limited palette for a cohesive look. Seal if you want added protection, or leave unsealed for a matte finish.
