I love cards that make a statement, and this BIG accordian card certainly does!  I decided to choose my favorite colors - birght, summery and fun!  I even pulled out my faithful die cutting machine.

Supplies:
Pop Tone Cardstock from CutCardstock.com  in Blue Raspberry, Sour Apple, Grape Jelly, Orange Fizz and Whipped Cream YUM!
Inks in Pear, Gypsy, Sunset and Lagoon by Close to My Heart
Up, Up and Away stamp set by Papertrey Ink
Don Juan Cartridge by Cricut
Tombow Mono Adhesive

Step 1:  Cut 4 pieces of your base cardstock (I used Whipped Cream Pop Tone) 5 1/4" x 11". 
Step 2: Score your card bases at 5 1/4" and 10 1/2", leaving a 1/2" at one end of three pieces.  Remove the 1/2" scored section from the fourth piece.
Step 3:  Place your card base pieces next to each other, with the 1/2" fold on the right side of each piece.  Adere the card base sections together, gluing the 1/2" flap of the first section to the back of the next section.  (The last section will be the piece that has the 1/2" flap removed).
Step 4;  Cut eight (8) 5"x5" pieces of colored cardstock for your layers.  Stamp each layer as desired. (I used kites, clouds and hot air balloons).
Step 5:  Accordian fold your card base mountain-valley-mountain style.
Step 6:  Adhere the 5"x5" pieces of colored cardstock to your card base. 
Step 7:  Cut letters for your message from cardstock.  I really like the way that the Pop Tone cardstock cuts using my Cricut machine!  I also cut a shadow for each letter in a coordinating color.
Step 8:  Adhere letters to their shadows, and adhere the letters onto your card base. 

I used a larger envelope (6 1/2" x 6 1/2" ) for the card to accomodate the thickness of several layers. 

Happy Stamping!
