Shadowing is a technique I picked up in High School and really didn't use it till college but it can be done in so many different ways and so many different effects can be achieved. I have done a very simple design here. I just love it.
Clouds are so cool and it this card the clouds make it. So easy to do. I updated the idea by using the Big Shot Oval Scallop. The scallop edges really take the clouds to a new dimension.
