What unique materials have you utilized in your arts and crafts projects?

During my younger years, I frequently engaged in arts and crafts to ease boredom. I recall incorporating some materials into my creations, including flowers, leaves, and twigs sourced from our family garden. In addition, I repurposed used boxes received on special occasions to add a unique touch to my projects. Have you ever utilized some unique materials in your own arts and crafts projects?
