I belong to Linda Heller's Stamping School, some of her projects are amazing. This one in particular where you can make a shadow image with your stamps using waxed paper.
I used Lost Lagoon CS and Stamp Pad. The stamp set is Traveler. The water I stamped off once and then stamped 3 times with Work of Art Stamp Set. I used Black Memento Ink Pad for the ship and shadow. Once you stamp the ship on your card you re-ink and stamp it on a piece of waxed paper. Turn it over, line it up and lay down on your card and touch with your fingers to press down (don't move or it'll smear), when you lift you have the shadow of the ship, cool huh? I used Red/White Bakers Twine and added the happy birthday tag (the happy birthday is from Something to Say Stamp Set). I cut two tags the same size, one in Whisper White CS that is stamped on with the happy birthday and the background one in Cherry Cobbler CS. The Whisper White CS with the ship stamped on it is layered onto another piece of Whisper White and then to the Card Base of Lost Lagoon CS. I really loved this technique and want to try it with other stamp sets. Thanks Linda Heller for always having such awesome lessons on your site!
