Sun Print Cards
After a few minutes in the sun on a sheet of light-sensitive paper, flowers and other natural forms leave their shadows behind. The images, which bring to mind old-fashioned botanical prints, can easily be trimmed into pretty blue cards and tags.
Select items whose images you want to capture. Lay a sheet of blue sun-print paper on a piece of cardboard atop a baking sheet, and place objects on paper; cover flat or lightweight objects with kit's acrylic sheet or a piece of Plexiglas. Place outdoors in the sun or indoors on a sunny windowsill (it will also work outdoors on a cloudy day).
In 1 to 5 minutes, the paper will fade, turning almost white. Immediately rinse with water for about 1 minute. The background will turn blue again. Let dry. Cut into cards, and write messages with white ink.
