When I first heard about knooking it was about 5 years ago. I thought it would be easy to learn this new technique. But at the time I was not ready for it. Now with the help of YouTube I am finally getting it. I also learned that its really popular in Europe. They even have metal knooks. This piece became a hat. I am going to learn how to purl soon. I also made a knook from a long wooden I had to use with bulky yarn.
