So, I did a little research, and I came across a company called Blue Sun Prints http://www.bluesunprints.com
I found a lot of fun choices. The rest of this of the Instructable shows what I did....
Step 1: Gather Your Supplies
The package of cyanotype squares
Assorted leaves: Fern, oak, and holly
Package of straight pins
I took my supplies to my makeshift darkroom (the bathroom), and turned on the light on my iPhone. Then... I pinned the leaves to the squares.
Step 2: Create the Print
Step 3: Reveal the Print
Rinse out the squares in cool water, until the water is clear.
Flatten out the squares, and enjoy the unique prints. Ooooohhhh..... Ahhhhh....
Now, to repeat the process with 19 more squares. What will I make with all these squares??? I think a quilt....
*****One final note: if the squares are not used in one session, seal them back up in their black plastic pouch, in a cool, dry place. Otherwise, you will end up with squares that are overexposed. *****
