Crocheting is a great way to use up leftover yarn and it's also an easy craft to learn. To get started, you'll need a crochet hook and some yarn. You'll also need a tapestry needle to help you weave in the yarn tails at the end of your work. To finish your crochet project, cut the yarn leaving a long tail and thread it through the last loop on your hook using a tapestry needle. This will cinch the last round closed.
