This list is for U.S. size crochet hooks.
Matching a hook size to a thread size can vary according to the brand of hook and the
gauge of the individual crocheter. For this reason, this list can be considered to be approximate
but can still be a helpful starting point and will often work out just right.
The higher the number of the thread, the thinner it is.
A popular thread size for crocheters who are just beginning to crochet with thread,
is thread size 10, used with a U.S. size 7 or 8 steel crochet hook.
