DIN A: Dipyramid-to-Parallelepiped (and Beyond)!

Using our standard fold pattern, one knife cut, and two pieces of tape, we can bring a single sheet of DIN A paper to life!

One sheet of DIN A paper, a straightedge and cutter, and two pieces of tape, are all that's needed. For a sturdier, more durable model, a heavy weight paper like the A5 used here which weighs in at 160 GSM, is recommended.

The fold pattern requires a total of 12 creases. I like to start with three folds which divide the sheet in 4 equal parts along the long length of the sheet. Then I make the three folds that do the same along the short length. Next, I make the two diagonal folds, corner to corner. And last, I do the four diagonals, from center of side to center of adjacent side. See photos.

To allow for our desired freedom of movement, a cut to the sheet must be made, and then tape is applied in such a way as to allow for the same degree of movement. See photos.

Figures to be found include:

The Dipyramid, the Parallelepiped, as well as several transitional forms, let's call them hybrids of these two. See video.

Same concept applied to A4 sized sheets of refrigerator magnets.
