Subject: Re: [Puptcrit] Strengthening mat board


I recall seeing one of Larry Reed's shows-fabulous mix
of shadow puppets, mask and dance-- I believe it was
about the life of one of the Khans of Asia. At the
time he was using plastic cut with a laser, and I
believe he was very happy with the result. I was able
to buy a souvenir of the show that was a plastic
sillhoute of o character. I think it is made from a
material called kydex, which is very a sheet stock
plastic. My experience with it is that it is very
durable, and not at all brittle. You mention bending
the Matt board 30 degrees. Do you need it to bend in
the show, or are you just worried about it wearing
out?
Lexan is another sheet stock plastic, super durable,
they make bullet proof glass out of it. When it is
thin, it is quite flexible, machines very well, but I
have only seen it sold clear. Sort of a disadvantage
for most shadow puppets...
