One more shaker card!
A big window filled with champagne-themed confetti !!!
Behind the transparent window (in the inside of the card) there's a perfect square of Oxygen Marble Prune paper (also used for another card see here) on mounting tape.
The cream cardboard in the inside is to write birthday wishes and it has been partially embossed with Sizzix embossing folder rick-rack (even if it's not clear from the picture).
