Sevenths (Fujimoto’s method)

This device cannot show the 3D view. Follow the step pictures and text below instead.

1. 

   1. A first guess: 1/8

   White side up; we will divide the bottom edge into seven. Fold the right edge to the left edge and unfold (1/2). Fold the left edge to that crease and unfold (1/4). Fold the left edge to the newest crease and unfold (1/8).

2. 

   2. Another round

   Fold the right edge to the 1/8 crease and unfold (close to 4/7). Fold the left edge to that new crease and unfold (close to 2/7). Fold the left edge to the newest crease and unfold (close to 1/7).

3. 

   3. The last round

   Repeat the same three folds once more: right edge to the newest crease, left edge to the new one, left edge to the newest again, unfolding each time. Now you have creases at 1/7, 2/7 and 4/7.

4. 

   4. Make 3/7

   Fold the left part over so that the 2/7 crease lies exactly on the 4/7 crease, then unfold. The new crease is 3/7.

5. 

   5. Make 5/7 and 6/7

   Fold the right edge to the 3/7 crease and unfold (5/7). Fold the right edge to the 5/7 crease and unfold (6/7). All six creases that split the edge into sevenths are made.

6. 

   6. Stand it up like a folding screen

   Fold the six creases from 1/7 to 6/7 into valley and mountain folds in turn, and stand the paper up like a folding screen: seven panels of the same width.
