How do you draw calla lilies?

To draw calla lilies, start by sketching the basic shape of the flower, which is a Trumpet-like structure with a curved, elegant form. Add the stem, ensuring it’s slender and slightly bent for a natural look. Detail the petals with gentle curves, emphasizing the smooth texture, and include a central spadix to represent the flower's reproductive part. Finally, refine the lines and add shading to give depth and dimension to your drawing.
