Hi Geoff,

Thanks very much for your quick and helpful advice!!! I did not think of
the water-based paint destroying the freeze-dried specimens, so that is an
invaluable tip! I have just checked on the local art shop site and looks
like they have this paint. I'll get a few colours and test them out. I
guess it will be hand-painting the leaves then, which is probably safer
anyway than trying to use the airbrush :)

Many thanks for your advice- what a life-saver!

Kind regards,
Emma
