Weight 4 yarns, a 3.5 mm (E) hook, fiberfill stuffing, and a yarn needle is all you need to crochet this elephant lovey.
Weight 4 yarn is the sweet spot, not too thin, not too thick, which makes it easier to hold and stitch with. It’s also one of the most common yarns you’ll find, so you won’t have to hunt for something special.
No safety eyes or extras required, just what you likely already have at home.
