Develop blueprint paper using Windex.
Order some take-out and rip the lid of the styrofoam container.
Pour adequate amount of Windex glass cleaner into container lid.
Find something that you can set your paper on so it doesn't get wet but still absorbs the Windex fumes.
Place inside plastic bag so the fumes are contained.
Find a nice black and white photograph that you will use for the contact printing.
You will need some blueprint diazo paper. I found mine on ebay for six dollars.
Place the blueprint paper sensitive side up on a flat surface. Then place the black and white photo face down.
Sandwich with a piece of clear glass.
Place in DIRECT sunlight for 4 to 5 minutes.
After you have exposed for 4 to 5 minutes you should see some discoloration that resembles your image.
Place paper sensitive side down on the rack in plastic sack for 5 minutes or more. Make sure to close the plastic bag so the fumes stay in.
Enjoy your Windex print.
