Gathered Top Curtain

I need curtains for every room in my basement (yeah, it's finally finished).  I really want to make them because I want to pick my own fabric- I've actually purchased the fabric for my boys' room and ordered some for the family room.  Needless to say, I've been searching blogs for cute curtain tutorials.  Found this Gathered Top Curtain from Make it and Love it- I LOVE it!!  SO cute- I love the gathered top... definitely one of my favorites that I've seen.
