the one hanging at tami with the cyber.wizard.institute was hand made with silkscreen paste, a net and hand cut paper.
here is the one i made with the sudoroom gang
i just photocopy the logo and cut with a blade.
it was good for one/two applications
with our stencil cutter and the transparency sheet we use for the ATtami stencils its very easy to do.
at the end you can catch a conductive inkjet printer in action
