2. Square Geometric Ashtray

A square geometric ashtray offers a modern and minimalist style. You will need air dry clay, a ruler, a cutting tool, and a smooth surface for rolling. Start by rolling the clay into a thick, even slab. Measure and cut a perfect square. Then gently lift the edges to form shallow walls around the square base.

Add grooves or indentations for cigarette rests using a small tool. Allow the clay to dry completely. After drying, sand the edges for a sharp, clean finish. You can leave it plain or use acrylic paints to highlight the geometric shape. This design is excellent for contemporary décor and provides a stylish alternative to traditional round ashtrays.
