CE marking is valid only for products for which EU specifications have been introduced. To affix the CE marking to your product, you must put together a technical dossier proving that your product fulfils all the EU-wide requirements. As the product's manufacturer, you bear sole responsibility for declaring conformity with all requirements.
This pattern allows for any size yarn as well as any size crochet hook. It is stitched from the toe to the cuff. This includes an example of a sock that measures 9.5 inches (24.1 cm) in length and 3.5 inches (8.9 cm) in width.
A size H hook is a good choice for this weight of yarn. If you have some crocheting experience, you may adjust the size of the hook to match your personal crocheting style. http://pad2.whstatic.com/images/thumb/0/0c/Crochet-a-Flower-Step-2-preview-Version-2.jpg/550px-Crochet-a-Flower-Step-2-preview-Version-2.jpg.
