I am not the creator of this fold. I found the directions on splitcoast stampers from Joelyn here. I just thought a step-by-step tutorial might be helpful to others.
Stamps (All in the Family, Family Accessories, It's Your Birthday)
4 1/2" x 11" card stock (for the base Tempting Turquoise)
2 1/2" x 5 1/4" card stock (for the pop-up message Groovy Guava & Whisper White)
Step by Step:
Decorate the front of the 4 1/2" x 11" cardstock. Then, flip it over and score at the following marks:
1", 2 3/4", 3 3/4", 5 1/2", 7 1/4", 8 1/4", 10"
At the 5 1/2" mark, cut down the score line from 3/4" to 3 3/4". This creates a slit in the center that is 2 3/4" long.
Fold along the score lines to make assembly easier later.
Mask off the bottom 1" of the 2 1/2" by 5 1/4" card stock. This inch will be hidden, so you want to make sure your design doesn't go that far down. In my case, I wanted to make sure the little boy would stand above this line.
Decorate the pop-up message. As mentioned in step 4, most of the grass at the bottom will be hidden when assembled.
Apply sticky strip to the bottom of the pop-up message on the front and back.
Slip the top of the pop-up message through the slit in the base.
Remove the protective film off the Sticky Strip on one side of the pop-up message and adhere to the bottom flap on that side. Be careful to keep the pop-up part straight during this process.
Repeat step 8 for the back side of the message. Once again, keep the pop-up message straight.
Prop up your card, because you are done!
