I have been experimenting with different coloured boards and am very happy with the effects. This is a collection of mostly Turf Mottlegills which produce black spores. They pop up during the summer in various parts of the lawn and in grassy areas in general.
This painting is made using wild mushrooms picked sustainably in the garden. The frame (purchased) is 30cm high x 40cm length x 4cm deep which can be hung. I used graphite grey card in a black frame with perspex.This is available in a black or white frame.
