In the video, a person is seen demonstrating how to make a pom-pom using a blue yarn. The person is using a crochet hook to create the pom-pom. They start by looping the yarn around the hook and then pulling it through to create a knot. They continue to loop and pull the yarn through to create a tassel-like effect. The person then ties the yarn off to secure the pom-pom. The video is shot in close-up, focusing on the person's hands and the crochet hook as they work on the pom-pom.
