This is sometimes called “real” grosgrain, milliner’s grosgrain, French grosgrain – but regardless of what it’s called, it’s essential when shaping an inner waistband. It’s also nicely strong for a waist stay. Petersham comes in various fiber contents, but this one – a combination of cotton and rayon – is my favorite. 1″ wide. Ships in yards.
