Below are instructions.
You'll need: Three - 12 in. by 12 in. pieces of card stock decorative paper that coordinate, preferably, two sided. This is for the box. And matching card stock at least 7 inches square for top of box. Glue stick, scissors, if possible craft paper cutter, embellishments for inside flaps, as shown above, treats and ribbon. If you want to mod podge pictures on a block, mine was a two inch square.
Cut one of your 12 by 12 in. card stock at 9 by 9 in. (this will be your bottom and largest piece) Score at 3 in. all round the 4 sides. Now cut out the right and left outer squares on top and bottom. Look at pictue below.
Take the second 12 by 12 in piece (this is the middle of the box) and cut to
8 1/2 by 8 1/2, score at 2 7/8 all around the four sides. Cut the right and left squares out from the top and bottom of paper like above.
The third 12 by 12 in. piece which will be the top layer. Cut a 8 1/4 by 81/4 square. Score at 2 7/8 all around the 4 sides. Again cut the right and left squares out from the top and bottom of paper like above.
Now you can decorate your flaps of paper with notes, embellishments and treats.
BELOW ARE THE INSTRUCTIONS FOR THE TOP OF THE BOX (THIS HOLDS IT ALL TOGETHER)
Cut a coordinating piece of card stock at 6 1/4 by 6 1/4 and score 1 1/2 inches all around your square piece.(if you are making a full box that needs to spread out a bit then cut your lid to 61/2 by 61/2, score the same.)
Cut in to the score line, two cuts on both sides. LOOK AT PICTURE. Glue these flaps inside to form a box top. Put your ribbons just on box top and decorate if you'd like. Now you can put the top to your gift explosion box and your done!
