There are some instructions on making carbon tissue in the archive. I found
the cheapest lining paper rolls from my local DIY store perfect for the job.<
Dear Peter,
My old friend Mike Shorter reckons that some lining paper contain
considerable amounts of formaldehyde as an anti-fungicidal agent which is
not a good idea for a tissue substrate, as your lining paper is cheap,
perhaps they did not bother to go to the expense of putting the
formaldehyde in, and therefore it works perfectly?.
It was great to meet you at Terry's fantastic Photogravure workshop.
