i tried a couple of yarn calculators online, and after combining their info, i got an average of 5.71 stiches per inch for the mountain colors line, putting it in the 12-14 WPI category, and therefore it's DK... or #3... or light worsted... such as vanna's glamour line. so there's my starting point? (you can tell i'm going to ask the joann's ladies for hand holding in the yarn aisles...)
i think it might be cheating... but i'm adding my stash 1 WIP at a time, on ravelry...
"i'm not great at advice. may i interest you in a sarcastic comment?"
