From paint to painting

The skin from an old tin of oil-based paint:
I thought it had “potential”.
So I carefully cut round it,
eased it from the tin and,
having scraped the still liquid paint
off the underside, set it to one side
on a sheet of art card.
I painted the card surrounding the paint skin
with a very dark yacht blue
recovered from the wreck of
the sailing cruiser Captain Fantastic
(a story for another day!).
The finished article,
having added chiaroscuro with artist’s oil white:
Blue Moon.
I originally thought I might add some stars…
not needed!
