Here is my take on this sketch and mood board.
I painted black gesso on the top and bottom of a white sheet of card. When dry, I painted Distress Crackle paint in picket fence over a mask.
The backing to the photos is washi tape and negative tape.
The Memory Maze lilies and swirls were painted with black gesso and antique silver glitter glue was smeared over the top.
