I believe so! I made two hats for DH recently, and one skein did it.
BUT...remember, some skeins have 215 yards, and some skeins have 92 yds!
That would make a diff.
So to knittingpatterncentral.com before you go shopping...find a basic kid pattern that you like, and check the yardage needed.
NEVER go shopping without a pattern or minimum yardage amts...like I do all the time...and have you seen the ridiculous stash I have?
