Here is how I do it:
- Cut an A4 square (20.8 * 20.8 cm) polyester fabric.
- Fixate the edges so they do not unravel, I used "Stiffy " for that, just a
millimeter along the edges; let dry.
- Carefully fold two flat cranes from 21 cm kami or just plain copy paper.
They must have the same angles etc.
- Unfold.
- Place the fabric between the two kami layers. Carefully fold all three layers
into a crane again.
The thickness of the fabric and the paper is why you want the fabric to be just
slightly smaller than the paper.
- Place on a flat dish and something flat on top of the flat crane.
I use two porcelain pie forms of different size so that they can be inside each
other.
- Put into oven preheated to 200 celsius for 20 minutes.
- Let cool completely, e.g. in the fridge.
- Unfold and take out the fabric. Refold.
- Hold in one wing tip and flap hard to unfold the crane.
- Throw it into the air, possibly bashing it up a couple of times, and it
refolds itself.
Done correctly, it will refold itself just by throwing it into the air.
You can do this in other fabrics like silk or cotton, but they will not refold,
and they are not moist resistant, but lose their creases when becoming wet. A
theatric taylor (if that is what they are called) recommends at least 60 %
polyester.
You may have to experiment a bit to find the optimal polyester. It should not
be too thin and soft, a little stiff is fine, but thick is not so good (for
this purpose).
In the fashion industry similar techniques are employed, often boiling the
object for an hour instead of using the oven. I find the oven easier to use, at
least for those smaller objects.
Those fabric cranes and the magical are great for entertaining in a show or
while teaching. Other models may be used, but the crane works particularly well
and is a well known and great symbol of origami. I have made e.g. roses and
birds from silk organza.
Enjoy,
