I only needed one panel as I was using it for the entryway window.  I love it!  It's very pretty and well made and grommets make it very easy to slide on the curtain rod.  I've received many compliments and they even look good from the outside of the house.  I would recommend this curtain panel without hesitation.
Update: I've had this curtain up for over six months and I love it! I love the beautiful, yet subtle wildlife theme and I hope they last for a very long time!
