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.
Crochet hooks made and sold in the USA use a lettering system for their sizes. As the letter gets further into the alphabet, the hook gets larger. These sizes vary from the 2.25 mm size B to the 16 mm size Q.
