This is a firm, fusible non-woven interfacing that is ideal for stabilizing shirt collars and cuffs. It gives a crisp, smooth, neat, professional look. It is best used with light to midweight woven and knit shirtings, including oxford cloth, chambray, gingham, madras, tattersail, pincord, flannel, polyester/cotton blends and kettlecoth. It has both a lengthwise grain for stability and a crosswise stretch for shaping.
