In the video, a person is seen holding a piece of pink yarn in their left hand and a crochet hook in their right hand. The person is demonstrating how to create a slip knot. They are pulling the yarn through the loop of the crochet hook, creating a loop that is tight enough to hold the yarn in place. The person then pulls the yarn through the loop again, creating a second loop. They repeat this process, pulling the yarn through the loop and creating a third loop. The person then pulls the yarn through the loop one more time, creating a fourth loop. The video ends with the person holding the yarn and the crochet hook, showcasing the completed slip knot.
