The Autotype tissue is certainly easy to use, but as you say the colour
doesn't suit many prints. It used to be possible to get as much as any
normal person would ever want to use by requesting a sample from Autotype,
I don't think I ever got round to using all of mine up!
The short reply to nze christian's question is that it is pretty easy (but
messy) to make carbon tissue and that there are some reasonably detailed
instructions in the archives. One set was posted by me, but I don't have
the details to hand, or time to search at the moment. It involves coating
paper with a gum solution which contains a pigment - I had best results
using Pelikan brand Drawing Ink - and sugar.
However there are others here (still here I think) who have much more
experience than me on this one.
