Cotton poplin, sometimes called broadcloth, is a plain weave fabric made with fine yarns and a dense construction. It doesn’t have the diagonal weave of twill fabric. Bed linens are usually made in this type of fabric. It has a very smooth, silky feel. Mélange is a specific type of yarn. It’s created by mixing different shades of the same color together before the yarn is spun. This gives a soft heather effect to the fabric and a casual look to the patterns.
