Well after some trial and error I finally have the Origami box video tutorial for you! I tried and tried to get captions on the video so I could put measurements on for you but i couldn't get it to work. Then I couldn't get the whole thing in one video so I have it as two parts.
Origami Box Video tutorial part 1:
I have the measurements here for you if you didn't catch them on the video:
1 piece of cardstock 11 7/8 x 8 3/4
Coordinating cardstock: Two pieces(2 7/8 x 2 7/8), Six pieces(1 1/4 x 2 3/4)
Designer Paper: Two pieces(2 3/4 x 2 3/4), Six pieces(1 1/8 x 2 5/8)
With the 8 3/4 part of the cardstock at the top of your paper cutter score at 2 7/8 and 5 7/8
Turn your cardstock a quarter turn so that the 11 7/8 side of your cardstock is at the top of your paper cutter. Score at 1 1/2 and 4 1/2 from each end. Score at 2 1/2" from the top of your cardstock to the first score line and from the bottom up to the first score line. Do this on both ends.
Cut along the score lines that are at the 2 1/2 down to the first score line on both ends and the top and bottom. Also cut along the cardstock between the 1 1/2 and 4 1/2 score line. This is what your cardstock should look like now.
Put adhesive on the back of the small flaps and bring them in to meet the edge of the cardstock on all four sides. This is what your box should look like now.
All you need to do is decorate your box with the designer paper and cardstock and place brads at the top with cord wrapped around to keep it closed.
I hope that makes sense! I got the original directions from Martha Stewart, a Stampin' Up! demonstrator from Florida. The directions were posted on the demonstrator website but I couldn't find them again. Let me know if you have any questions.
