International Crochet Standards

International Crochet Standards
The Craft Yarn Council of America have set up a series of guidelines to bring uniformity to yarn, needle and hook labeling and to patterns, whether they appear in books, magazines, leaflets or on yarn labels. Their goal is to make it easier for you to select the right materials for a project and geplete it successfully.
Standards are guidelines for industry manufacturers, publishers and designers to assist them in preparing consumer-friendly products. With the cooperation of manufacturers, publishers and designers, these changes will be implemented over a period of time as products and packaging are redesigned and new books and leaflets are published.
It is the Craft Yarn Council of America's objective to design global standards and guidelines that will be used by gepanies worldwide. To this end, they have reached out to individuals, manufacturers and trade associations in the United Kingdom, Germany, Italy, France, as well as in Australia and New Zealand to ask for their input.

Crochet Hook SizesThe Craft Yarn Councils hook manufacturers have agreed to make metric (millimeter/mm) sizing more prominent on packaging. U.S. sizes - numbers and/or letters, will also appear on packaging.
More prominent labeling of metric sizing, which is an actual measurement, should help eliminate consumer questions about the differences between the letter and number sizing of some hooks. With the cooperation of manufacturers, publishers and designers these changes will be implemented as packaging is reprinted and new patterns are published.
