Don't use linseed oil when you are going to expose them to a hot light
source.  I had a friend whose puppets ignited from the heat of the light she
was using. Nancy

Subject: [Puptcrit] Strengthening mat board


Folks,

I'm building shadow puppets. I'm using a new kind of desktop laser to
cut the many holes. Traditionally, wayang are made of parchment - ie
leather, but the laser has problems cutting leather . I wonder if there
is a way to strengthen mat board materials. I understand that persimmon
juice is used in Japan to waterproof and strengthen paper used for
stencils, but I cannot find a source for it here in the states. I
wonder if linseed oil would be at all helpful. Mat board is both a bit
too rigid and to fragile - fold it more than 30 degrees it breaks and
rips. I wonder if sandwiching Tyvek between two pieces of board might
work better - it would be certainly have more tensile strength, and be
harder to rip.

Plastics seems to be where I am headed - but it too can be brittle.

In short, I'm looking for something that is tough like leather,
flexible like leather, perhaps translucent like leather, but ain't
leather.

Suggestions?

Cheers,
DMCG
