There are several materials and tools that can be used to create textured art. Here are some options:

1. Joint compound or drywall mud: This is a popular material for creating texture on canvas or other surfaces. It can be applied with a putty knife or other texturizing objects like forks, combs, or decorative frosting tools.

2. Spackle: Similar to joint compound, spackle can be used to create texture on canvas or other surfaces. It can be applied with a putty knife or other texturizing objects.

3. Paint: Paint can be used as a basecoat or to add color to textured art.

4. Canvas: A stretched canvas can be used as a base for textured art. It can be repurposed from an old painting or purchased new.

5. Texturizing objects: These can include notched trowels, forks, potato mashers, spaghetti serving spoons, and frosting spreading knives.

6. Sealant: A clear sealant or colored spray paint can be used to protect the finished artwork.

Overall, the materials and tools used for textured art can vary depending on personal preference and the desired outcome.
