A Card With a Difference

My sister's birthday was coming up and I was looking for inspiration of what to do for her card this year.
As I flicked through a card making magazine, I found the perfect idea.

(Inspired by Paper Essentials UK Issue 108)

It's a shaped card, but doesn't have an are inside to write on - I just wrote on the back.

By the way - she loves it!! And even said if she found a dress like it she would wear it!!
