These are the instructions for making a Crane.  You will now be  
practicing the ancient art of folding paper called Origami.
Once you learn how to fold the crane, you will soon discover why 
folding 1000 of them can be meditative endeavor.

     You must start with a square piece of paper.  This is 
essential, that all 4 sides are exactly the same length or the 
folds will be off and you will end up with a very messy looking 
bird.

     The Degas files CRANE1.PC3 and CRANE2.PC3 accompany these 
instructions.  Degas was chosen for most ST users have some 
program or utility that can be used to visualize Degas files. 

     To understand how to use the diagrams, the dashed lines are 
where you fold the paper.  The fainter, dotted lines are creases.  
The numbered steps correlate exactly with the same numbered 
diagram.  Hopefully this will be enough to get you through the 
folding.  

1.  Fold the square piece of paper along a diagonal.  You can fold 
along the other diagonal to make an X in creases on the sheet.  
This will help you orientate the folds and maintain symetry.  Keep 
the paper folded along one diagonal to get a doubled triangle.

2.  Take your triangle and fold the outer corners into the center 
peak of the triangle.  You should end up with a square that looks 
like diagram 3.  

3.  Take the corners you brought in towards the center and tuck 
them into the middle.  This is tricky.  If you did it correctly, 
the corners you brought into the center in diagram 2 and 3 should 
now be up inside and not accessible.  This is called 'reverse' 
folding.  What was on the outside is now inside.  

4.  If you did the previous step correctly, you should end up with 
something that looks like 4.

5.  Bring in the outer corners and fold into the center.

6.  Fold the top triangular flap, not covered by the corners you 
brought into the center in step 5.

7.  If you executed step 6 correctly you should have something 
that looks like that pictured in 7.  

8.  All these previous folds were prepatory, to make creases that 
will be your guide in step 9.  Your creases should look like 
those in diagram 8.

9.  You now take the bottom flap and lift up to make a diamond as 
shown.  You fold in the edges of the paper towards the center, 
along the previous creases you made.  You should have something 
that looks like diagram 9.  Repeat the same proceedure on the back 
side.

10. You should now have a diamond shape as shown, with the bottom 
of the diamond being two independent pieces.  In explanation, 
there should be two separate long pieces as part of the bottom of 
the diamond.  Now you fold the outer edge in towards the center, 
which is the gap.  You should now be at 11.

11.  Repeat step 10 on the back.  

12.  You should now have something that looks like diagram 12.

13.  The two thin pieces that you made in steps 10, 11 and 12 are 
now 'reverse' folded by pulling them up, away from the gap, 
actually making it a huge gap.  What was on the outside is now 
inside.

14.  Now 'reverse' fold one of the tips to make the head of the 
crane.  

15.  This is your crane.  You can put finishing touches by folding 
down one or both wings.  You can make it 3-D by spreading the 
wings out to the sides.  There is a hole in the bottom of the 
crane, which you can blow into to inflate the body.  This is the 
finished, classical product.  Of course if you make it 3-D, you 
cannot mail the crane.
