Ghosts of Summer - new greetings cards

I have been making use of some sun-prints I made last summer... Laying various plants onto light-reactive paper, then developing the prints in water, I ended up with some very lovely and etherial images in blue & white. I have mounted these onto large white card blanks and have started to call them my "Ghosts of Summer" cards because they seem very much like that, a white shadow, and slightly faded like a memory.
