The stamp set that I used is called Petal Pack. It has a lot of fun images to choose from. The sentiment comes from one of TAC's Level A hostess sets. (you can get it for free when you have a $100 FunShop!)
There are so many different areas that you can apply your white pen to. I made up this little chart to show my guests just a few of the areas that they could fill in. Each one gives a different look.
