19 mm crochet hook

A 19 mm crochet hook equals US size S and has no old UK number. It is the recommended hook range for jumbo (7) yarn, and crocheters typically choose it for jumbo chenille blankets, rugs and projects worked with multiple strands. Always check gauge with a swatch, because tension varies between crocheters.
