"Half Tri-Fold" Card?

Um, not sure really what it's called so let's just call it that for now.  If I could remember where I saw this idea from, I'm sure the name would be there.  But I don't.

This is the other card I will be using for one of the two upcoming weddings.  Again, notice the simplicity of the card, yet it doesn't look boring.  Layers are an easy way to really dress up a card.

Take a look at the pictures of the front and back of the card, and when it's opened up.
