Crochet Hooks
Crochet hooks are made of steel, plastic and alloy metals. Each hook is used with a set size of thread unless otherwise stated in the pattern. A pattern should specify a hook size and a tension, so a larger or smaller hook may be required to achieve that tension. If the crocheting is too loose, use a smaller hook, if the crocheting is too tight, use a larger hook. The table below is to be used as a guide only for thread and hook size.

American Thread / Yarns
American threads usually use the same sizing as our own for crochet cotton sizes such as our number 10, 20, 40, etc. shown as No 10 or #10 etc. Bedspread weight yarn generally refers to our No 10 crochet cotton but some patterns may use thicker yarn such as No 5 or even our 4 ply cotton, so check hook and tension specified.
Yarn sizes however are generally provided as a weight of yarn such as worsted weight, sports weight, etc. The following provides a very basic guide for determining the yarn to use and should be used in conjunction with any specified hook size and tension.

When using an American pattern that requires worsted weight yarn and you want to use 8ply yarn and a 4.00mm hook, remember the article will probably turn out smaller, so from the tension, add more stitches / rows to achieve the required size.
