This is a birthday card I made for Scott's younger brother, Chris. I thought his birthday was today, but it was actually yesterday (sorry, Chris). As you pull the ribbon, it sets the 'waterfall' in motion, revealing a series of stamped images and finally your message. Instructions can be found here if you're interested in creating one for yourself.
A view of the card, "in-motion:"
And finally, the last image. You can put the sentiment on the pull-out strip so that it appears as you pull on the ribbon. Alternatively, you can use the whole thing as a card front and put your sentiment on the inside of the card.
Thanks for looking!
