Sizzix Pop Up Cake

I made this Sizzix Pop-Up Cake card for my Stampin' Sister's birthday.  It is her last birthday in her 40's.  She doesn't turn 49 for another couple of weeks, but since we are going away next weekend to the Stampin' Up! Seattle Regionals, I wanted to give her her birthday gift for the trip.  As soon as I saw it, I knew it was her because it in was her favourite colour-- purple.  I am always good at "feeding her habit"!  Another good reason for this gift is that she is a Fitness Guru...
