Re:a process of heliophotocopying I'd like to see

You can! its not hard to by "sun print" paper... i have some, my neices and nephews thought it was great.. they put down flowers and ferns, on the paper, covered with glass, exposed to the sun, and 'finished' by rinsing with cool water.. I got them in an educational supply store.. i can't remember how much they cost.. (but i didn't balk, and i am so cheap!)
