In the studio yesterday, the tissue & paper sample had dried from last week & was ready to work on although I was a little apprehensive regarding whether it was going to achieve what I hoped. I used some crayons & ink & left it to dry for a while.
Above is how I then saw it but knowing something more would appear under specific lighting, I photographed the next step! (sorry for the orange & green 'bits' beyond the black paper upper right, but its not part of the design!)
