Crafters, sewists, and hat makers, listen up! This is Petersham ribbon, which is different from regular grosgrain. It's made of rayon, so it has a soft drape and is skin-friendly. The key feature is the scalloped edge – this allows the ribbon to be shaped and curved smoothly, unlike grosgrain which has a sealed, rigid edge. It's thick, flexible, and doesn't stretch. This specific one is 2 inches wide (about 5 cm) and comes in a 6-yard length, which is plenty for projects. It's washable, colorfast, and has minimal shrinkage. It's perfect for millinery (hat making), as belt facing, for corsets, along waistbands on skirts or trousers, shoe binding, or any craft where you need a ribbon that can mold to a shape. A really versatile, professional-quality trim that's a staple in serious sewing rooms. If you've never used Petersham before, it's a game-changer for clean, shaped edges.
