I saw a tutorial for this card about 2 years ago and have been meaning to try it for just that long. One of my nieces turned four over the weekend, so I decided to give it a shot. I didn't remember where I saw the tutorial, but I remembered the basics. I veered from the tutorial and put the "bulk" that creates the shaker effect on the outside of the card rather than the inside. I use dimensional foam a lot on my cards, so it seemed for logical for my needs. By the way, my niece is IN LOVE with the card and has told me "thank you" about a million times!
