From the French, meaning ‘coarse grain’, a heavily ribbed ribbon or fabric where the weft is heavier than the warp, woven from silk, cotton or rayon in a wide range of colours. Grosgrain is used for trimmings, as stabilising tape, and hatband stripes are made of grosgrain ribbon.
Grogram is the historical, fabric version of grosgrain, a coarse country fabric woven from wool, silk, wool and mohair, probably no longer made now that finer cloths are plentiful.
