Cascade's Cherub Chunky is a heavy-worsted- to chunky-weight, plied, 55% nylon / 45% acrylic yarn with 136 yards per 100 gram pull-skein. This soft and durable yarn is machine washable and dryable, making it a great choice for baby and children's clothing, blankets, and other hard-wearing items. Labeled as a chunky by the manufacturer, we reccommend treating Cherub Chunky more as a heavy-worsted weight yarn, and choosing needle and hook sizes accordingly.
