Now, let's dive into the messy fun of creating your homemade gesso masterpiece!

Step-by-Step Instructions

In a clean container, combine 3 parts cornstarch and 3 parts baking soda. This forms the base of your gesso mixture. Using a plastic spoon, add 1 part glue to the cornstarch and baking soda mixture. Stir thoroughly until smooth and well combined.

For a white gesso, add 1 part white acrylic paint to the mixture. Stir until the color is evenly distributed, creating a creamy consistency.

Slowly add 2-3 parts water to the mixture, adjusting as needed to reach your desired consistency. The gesso should have a smooth, paint-like texture that spreads easily but is not too runny.

To ensure your gesso is just right, apply a small amount to a test surface. It should provide a gritty texture for your media to cling to.

If the gesso is too thick, add a bit more water. For a thinner consistency, mix in additional acrylic paint or cornstarch.

Storing Your Homemade Gesso

Tips for Using DIY Gesso:

  • Experiment with Texture: Play around with the amount of cornstarch and water to create the perfect textured surface for your artwork.
  • Customize Your Colors: For a colored gesso, swap out the white acrylic paint for your preferred color. Get creative with hues that complement your artwork.
  • Apply in Layers: Allow each layer of gesso to dry completely before adding additional coats. This creates a solid foundation for your masterpiece.
