What is the Paper Basket?
...... 
The basket is a container shaped like a rectangular solid
folded from a square sheet of paper. 
Folding of the
Basket top
1
....... 
Take a sheet of paper of the size A4 (8 1/2" x 11").
Paper used for ink jet printers will do.
Fold the upper half down on the red line.

2
... 
Cut off the lower strip.

3
... 
The result is a square.

4
... 
Fold downwards on the red line.
The result is a rectangle. 
5
... 
Fold downwards on the red line and backwards on the blue
line.
The result is a triangle.
...(redvalley,
bluemountain)

6
...... 
Turn the paper 90 degrees and open it. The thumbs must
be inside. Lay the upper and the lower parts on each other.
The result is a square. 
7
... 
Fold the upper sheet on the red line and refold.
The centre of the square is marked.

8
... 
Fold upwards on the red line.

9
...... 
Roll the strip upwards (green), press the roll flat,
when it has reached the upper triangle. (If you have no practise, you should
prefold by several halvings.)

10
... 
Turn the paper over.
There is a free square.

11
... 
Repeat the steps 8 and 9. 
12
... 
Fold the upper right layer on the red line to the left.
There is a square again.

13
... 
Fold upwards to the centre three times on the red lines.
There are three triangles meeting in the centre.

14
...... 
Fold upwards a rectangle on the red line, thus cover
the meeting place of the three triangles.

15
... 
Turn over the paper.

16
... 
Fold the upper right layer on the red line to the left.
There is a square again.

17
...... 
Fold three times on the red line. Three triangles meet.
Cover the meeting point by folding upwards on the red line. 
18
...... 
Turn the nearly finished basket 90 degrees, open it and
form a container.

19
The container becomes a basket, if you form a handle.
...... 
Cut a handle from the strip of step 2. It is best to
make two layers.
Fasten the ends of the strip by pushing them under the
rolls of step 9/11. You can carefully unroll them for a moment.

It is more elegant, if you already roll the strip together
with the triangles in step 9 and 11. But I prefer the way described above
because the strips become disturb afterwards.
Some Mathematics

...... 
If you unfold the paper basket, you get a square with
the pattern on the left. It is coloured so that you can recognize the inner
side of the basket in white.
The basket is the half of a cube.
If the side of the square has the length a, the edge of
the cube is sqrt(2)/4*a. This is about 0,35*a.

The paper basket belongs to the classic paper foldings
like the paper boat, the paper
pigeon, the fortune teller, the paper
purse, the paper cup and the
magic bag.
In all cases you start with rectangles and you get figures
without cutting or gluing. This is the principle of origami.
In my childhood, later on for my children and now for
my grandchildren the basket was and is the number one of our foldings :).
