You have to look at yardage. If your pattern says 3 balls--three balls of what yarn? How many yards of yarn does each ball of that yarn have?
A skein is yarn that has not been rolled into a ball, and a ball is what you can knit from.
"Trust the pattern!"
Time flies like an arrow, but fruit flies like a banana.
Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
