Their natural beige color gives them a rustic appearance without requiring additional coloring.

If you want a different look, they can also be painted before being used.

Pistachio shells can be surprisingly versatile during holidays.

Painted shells can become parts of Christmas ornaments, autumn decorations, floral arrangements, or handmade gifts.

For example, several shells can be assembled into a flower, painted in seasonal colors, and attached to a wreath.

The possibilities depend mostly on your creativity.

And because the primary material is something you already have in your kitchen, the project can cost very little.

Pistachio shells can also be useful for simple science and nature-related activities.
