The best material for a baking apron is typically cotton or a cotton-polyester blend. Cotton is soft, breathable, and absorbent, making it ideal for handling flour, sugar, and other ingredients. It’s also comfortable for long hours of baking. Some aprons may be made from thicker fabrics, such as denim or linen, which offer durability and a stylish look, while polyester blends can offer a more wrinkle-resistant option.
