Measurements and directions from from Split Coast Stampers
Start with a 8 ¼" x 9" of card stock
Score at 2 1/8, 4 ¼, 6 3/8, and 8 ½ across the long side
Then score down the short side at 2 ¾
Cut this piece down to 6 inches, so what you have left is the box card piece of 6" x 9"
Take the piece you cut off (left over is 2 ¼ x 9") and cut it to 3 1/8". So you have 2 ¼ x 3 1/8" piece and then cut in ½. These two piece will be the inner separators to be able to attach your pop up designs. (In my case it was flowers and the sentiment)
Take the 6 x 9" piece and cut up to the score lines to make a box flaps
Fold down only three flaps so you have a solid back with the tab and it forms an open type box
Take the little separated pieces and glue them inside the box to separate the flower elements.
I made a belly band 2 ½" not shown
