Standard Yarn Weights
When describing my yarns, I have adopted these guidelines and standards from the Craft Yarn Council, which I am using with their kind permission.
They are provided to give you sense of their thickness and the needle or hook size you would normally use with such a yarn. Obviously, they are a guide only and you can use other sizes to achieve a variety of looks with your projects, depending on the pattern you are using.
I hope you find this information useful. Please do get in touch if you have any questions and I will try to advise you as best as I can.
