Cotton is an essential material when it comes to building your bedding retreat. Not only is it comfortable and breathable, but it's machine-washable, so it's a breeze to quickly and easily refresh. Take this sheet set for example: Crafted from 100% cotton with a 300 thread count, it offers a crisp white hue accented by embroidered stripes for a touch of texture and contrast. Includes flat sheet, fitted sheet, and two pillowcases.
