Diagonal Thank You

I'm sure for most card makers, creating a card that can actually be mailed is a huge challenge!  We like layers and embellies and more paper is better right?  Well this week I really needed to send out some thank you cards in the mail, so I scoured the blogs I follow for ideas that pop but are also flat!  I found a tutorial from Maile Belles that was quick, flat, AND cute.  Just what I was looking for!  Now I can actually get some cards mailed out!
