The difference between

DK, SPort, and worsted weight yarn. i mean is there really a difference between the 3? they all look the same. so i’m just wondering if i could used one when another is called for?

Worsted weight is about twice as thick as sport, and dk is somewhere in between. I think that with a possible needle adjustment, you can hope to substitute dk and sport for one another, but probably not worsted.
