Hi,
AM I understanding this correct, that Worsted weight yarn is usually thicker than Sports weight?

Thank you!

yes, that's correct. :)

I've seen this type of description on some yarns - in this case they probably mean a sportweight yarn that's been worsted spun. Don't ask me what "worsted spun" means, though...I'm sure someone here know more technical stuff than me!

ETA: It looks like you were just asking if worsted is thicker than sportweight. Sorry for the TMI!

Just in case you might want even more tmi...
