Many years ago I used to paint on glass, so thought that this challenge would be right up my street. Unfortunately all my paints had dried up, so putting on my thinking cap I came up with the following. Sharpie pens on acetate. It took a bit of playing with as the pens act differently on plastic and can only be laid down once, so no shadowing etc and with a very careful laying down of colour, otherwise it streaks. Being in a whimsical mood I doodled the following.
I then taped it to my conservatory window. Rather a dull day though, so not shown to its best.

Wishing all the lovely CT'ers blessings for a very happy and positive New Year.
