Wetting water soluble felt pen(orange!) made an interesting effect- dissolved all my writing – so the end result is not what I had in mind!
BTW I loved today’s combination of cup, saucer, pot and table ‘number’ pot (thanks to the waiter for trying to find something different for me- what service!!! I think he was disappointed that I had it before! Interesting to compare the state of the pot today with the last time I sketched it)
