Denim is a type of sturdy cotton fabric that is commonly used to make jeans, jackets, skirts, and other clothing items. It is known for its durability, strength, and versatility.

Denim fabric is made from cotton fibers that are woven using a twill weave. This weave creates a diagonal ribbing pattern that gives denim its characteristic texture and strength. The fabric is traditionally dyed with indigo, which gives it a blue color that fades over time with wear and washing.

Denim fabric can vary in weight and thickness, from lightweight and stretchy to heavy and rigid. The weight of denim is measured in ounces per square yard (oz/yd²), with heavier denim generally being more durable and long-lasting. Denim is also available in different colors and finishes, such as acid wash, stone wash, and distressed.

In addition to clothing, denim is used in a variety of other products, including bags, upholstery, and accessories. It is a versatile and durable fabric that can withstand a lot of wear and tear.

When using denim fabric, it’s important to prewash it before cutting and sewing to prevent shrinkage and bleeding of the indigo dye. It’s also important to use the appropriate needle and thread for the weight and thickness of the fabric to ensure the best results.
