In the video, a person is seen holding a crochet hook and a piece of yarn. The person is using the crochet hook to create a loop with the yarn. They then proceed to pull the yarn through the loop, creating a knot. The person repeats this process several times, creating a series of knots along the length of the yarn. The yarn appears to be a light blue color, and the crochet hook is a darker shade of blue. The person's hands are visible in the frame, and they seem to be skilled at handling the yarn and crochet hook. The background is a plain white surface, which provides a clear contrast to the blue yarn and crochet hook.
