These are the most wonderful, comfortable, and lightweight afghan hooks. They are made of a wonderful aluminum and are truly "Easy Glide". A pleasure to use with any type of yarn. They come in a nice range of sizes so that most of your Tunisian Crochet projects will fit comfortably with projects that are just a few inches in width to three times the length of the hook. Look no further. These afghan hooks will give you a most pleasant experience.
