How to Crochet Ribbing at the End of a Project
by Little Monkeys Crochet

Crocheting ribbing and then working on from there is easy... but sometimes you need a section of ribbing at the end of your project. Perhaps you want to add ribbing to a top-down hat, or you need ribbing on both sides of a pillow or blanket. Forget crocheting it separately and then sewing it on... crocheting it right onto your project is easy!
