I stamped each of the four stamps from the Holiday Trinkets set (More Mustard, Baja Breeze, Real Red and Kiwi Kiss with a Real Red marker), sponged around the Whisper White edges and layered on 2" squares of card stock that matched the ink.
The key to the waterfall card is the 2" x 7 1/2" strip to which you adhere the 2" squares, spaced 3/4" apart. The only adhesive on the long strip is on the bottom of the top piece under the star square.
When you pull the ribbon at the bottom, it flips up each square as they hit the horizontal strip attached with brads.
Best of all, you can open the card and write a nice, long message to a terrific friend!
