Using a Mold to Make Paper Mache: Creating Unique Art Pieces Effortlessly


Creating art with paper mache opens up a world of possibilities. From masks to sculptures, the versatility and affordability of this medium make it a favorite among artists and crafters alike. In this article, we will explore the advantages of using a mold for paper mache and how it can simplify the process of making multiple copies or mass-producing your designs. We will also guide you through the steps of creating a silicone mold and using it to make stunning paper mache masks or sculptures.

Why Use a Mold for Paper Mache?

2.1 Creating Multiple Copies

2.1.1 Saving Time and Effort

Imagine you have designed a paper mache sculpture or mask that is highly popular among your audience. The demand for your creation is overwhelming, but recreating each piece from scratch would be a daunting and time-consuming task. This is where using a mold becomes a game-changer. By creating a mold of your original model, you can effortlessly produce multiple copies without having to start from scratch every time. This not only saves you valuable time but also minimizes the effort required for each piece.

2.1.2 Meeting Demand for Popular Designs

For artists or crafters selling their creations on platforms like Etsy, having the ability to produce large quantities of a popular design is essential. By using a mold, you can easily meet the demand for your highly sought-after designs, ensuring customer satisfaction and boosting your business prospects. Whether it's masks, sculptures, or any other paper mache creation, a mold allows you to replicate your design flawlessly while maintaining consistency.

2.2 Facilitating Mass Production

2.2.1 School or Community Events

From school plays to community center events or vacation bible schools, there are numerous occasions where multiple individuals need to wear masks or costumes. Instead of making each piece individually, using a mold can streamline the process. The mold allows one person to create the initial design while others can produce identical copies using the mold. This approach saves time, allows for consistent quality, and ensures that everyone participating in the event has access to the necessary props or costumes.

2.2.2 Business Opportunities

If you are considering selling your paper mache creations, having the ability to mass-produce your designs becomes a significant advantage. By using a mold, you can efficiently churn out multiple pieces, increasing your inventory and expanding your business prospects. Whether for craft fairs, art galleries, or online sales, a well-constructed mold allows you to produce high-quality and consistent pieces that meet the growing demand for your unique creations.

Choosing the Right Material for the Model

Before diving into the mold-making process, it is crucial to choose the right material for your model. Two common options for sculpting are wet clay and oil-based clay, each with its advantages and considerations.

3.1 Wet Clay

Wet clay is a popular choice for sculpting due to its workable nature and ability to hold fine details. It can be sculpted effortlessly and remains pliable until dried or fired. Wet clay is particularly suitable for intricate designs or when you want to capture specific textures or contours. However, it requires careful drying and may shrink or crack during the drying process. Additionally, wet clay may not be suitable for all types of molds, so it is essential to consider the mold-making material when working with wet clay.

3.2 Oil-Based Clay

Alternatively, you can use oil-based clay, which remains soft and malleable indefinitely, making it an excellent choice for mold-making. Oil-based clay does not dry out or become brittle, providing a stable and consistent model for creating molds. This type of clay allows for easy adjustments and modifications, making it ideal for artists who prefer working iteratively or want to create intricate designs. However, oil-based clay may require additional sealing or preparation to ensure proper adhesion when using certain mold-making materials.

Making a Silicone Mold

Creating a silicone mold is a critical step in the mold-making process. Silicones provide excellent detail reproduction, flexibility, and durability, making them an ideal choice for mold-making.

4.1 Sculpting the Model

Start by sculpting your desired design using either wet clay or oil-based clay. Be mindful of intricacies, as certain features may create undercuts that could trap clay inside the mold. To avoid this, remove any long, thin areas such as ears, as they can hinder the molding process.

4.2 Preparing the Clay for Molding

Before applying the silicone, seal the clay model using a clear drying spray or appropriate sealant. This step prevents the silicone from sticking to the clay and ensures a clean release once the mold is cured.

4.3 Applying the Silicone

Begin by applying a thin layer of silicone to the model using a chip brush. This initial layer allows for easy removal of any trapped air bubbles. Pay close attention to undercuts and detailed areas, making sure to remove any air bubbles using a toothpick or a small tool. Once this layer is tacky, apply a thicker layer of silicone, ensuring complete coverage and smoothing out any brush marks or imperfections.

4.3.1 Ensuring Smooth Surfaces

To achieve smooth surfaces on the inside of the mold, use a soft brush dipped in water to brush over the silicone before it cures. This technique helps create a clean and polished finish that allows for easy release of the paper mache casting.

4.3.2 Dealing with Undercuts

When working with undercuts, such as long ears or protruding elements, it is crucial to create dams or barriers using clay or other materials to prevent the silicone from flowing underneath and creating difficult-to-remove undercuts. Taking this precaution ensures a clean and straightforward mold release.

Creating the Paper Mache Mask/Casting

After successfully creating the silicone mold, it's time to move on to the paper mache casting process. This step involves layering paper strips or paper mache clay over the inside of the mold to create a sturdy, lightweight, and highly detailed finished piece.

5.1 Mixing the Paste

To make the paste, you have the option of using wood glue or flour and water paste. Wood glue is a popular choice due to its quick-drying nature and the strength it provides to the final piece. However, if you prefer traditional paste, experiment with the flour-to-water ratio to ensure a paste that dries completely without causing warping or changing the shape of the paper mache.

5.2 Layering the Paper Strips

Start by applying small pieces of paper strips soaked in the paste to the mold, focusing on detailed areas first. Gradually layer larger pieces, smoothing them out and ensuring good adherence to the mold. This method allows for better control over the paper placement and avoids trapping excessive air bubbles between layers.

5.2.1 Adding Detail and Texture

To add detail and texture, such as fur marks or eyebrows, apply paste on the desired areas and use tissue paper or air-dry clay to create ridges and creases. These small touches will bring your paper mache creation to life, adding depth and character to the final piece.

5.3 Drying and Releasing the Mold

Allow the paper mache to dry thoroughly, both on the surface and inside the mold. A well-dried piece will easily release from the mold without any sticking or distortion. Additionally, ensuring complete drying prevents any dampness or moisture from causing warping or mold growth in your finished paper mache creation.


Using a mold for paper mache opens up a whole new realm of possibilities for artists, craftsmen, and even educators. Whether you want to create multiple copies of your favorite design or engage in mass production for business purposes, having a mold simplifies the process and ensures consistency. By following the steps outlined in this article, you can confidently create silicone molds and produce stunning paper mache masks or sculptures. So, embrace the versatility and convenience of molds and let your imagination run wild in the world of paper mache art!
