A type of weave that is used a great deal for bedding, percale is made of either 100% cotton yarns or a cotton-polyester yarn blend. The “thread count” of a percale fabric is calculated by counting the threads going in both directions inside one square inch of the fabric. Note that a high thread count percale blend won’t be as sumptuous as a lower thread count that is completely constructed of cotton. Furthermore, due to dye saturation, a dark colored cotton percale will feel stiffer than a lighter colored cotton percale with the same thread count.
