Sunlight Paper

I found this paper in hobby lobby. I did this in high school in my photo class, I used a dead squirrel....but this time i used pretty flowers.
It's really simple all you do is put stuff on your paper....flowers, leafs, feathers, dead squirrel, anything! then put in the sun till the paper is light light blue. then clean it off with water. that's it! so fun to do!
