Yarn weights

Alas, in the yarny world we may speak English, but when it comes to yarn weights (and crochet terminology) we are divided by a common language... I say Aran, you say worsted, you say DK, I say 8 ply...you say single crochet, I say double crochet....

Here's a link to the US Crafts Council Standards and Guidelines for Crochet and Knitting* document on yarn weights, terminology and more.  A useful reference, recently updated to include jumbo weight yarn.
