When folded flat, the box measures 6 1/2" wide, and 4 3/4" high. The box is cut in two parts. I created a file in Design Space for the Explore for the basic shapes (You can also cut them by hand)
Top shape is 9 1/2" wide and 3" tall. The two shapes on the left are the inserts for inside the box to hold all the elements. They are 5 1/2" x 1 1/2".
After they are cut, I score the two strips at 1/2" in on each side, so at the 1/2" mark and the 5" mark. The second piece is scored vertically at 1/2", 2 1/2", 7" and 9" Turn the piece lengthwise, and score at the 1 1/4" line all the way down. The back panel has no score lines.
On the bottom piece in the above photo, I cut the fold line to the middle score line, and then on an angle towards the main piece. Did this on both sides of the piece. The part that is left is for attaching to the back of the box. I also snipped the vertical fold lines at the top, these are the box parts that fold out.
Fold on score lines, and this is what it will look like.
Add score tape (or your adhesive of choice. Score tape is very strong...you don't want the box to fall apart. Attach to back panel.
Here is your assembled box. Add your decorative paper and box is done. Add elements and that's it! I've made other boxes that measure 5" high by 6" wide when folded flat. I make these in 2 pieces, both measuring 5 x 6 1/2. The 1/2 " is the flap, when trimmed as above, attaches to form the box.
Hope this is information is clear and helpful. If you have any questions, just post in comments and I will try to answer.
Have a great day!
