Tear or clip the paper into small pieces, the smaller the better.
Pour some hot water over the paper shreds to soak. Let the this soak for a couple hours.
Place a cup or so of the paper scraps along with a couple cups of water into your blender. Blend until the paper is pretty much a pulp. Repeat this until all the scraps are blended.
Add red food coloring to the water and stir it into the paper pulp.
Hand squeeze the pulp, getting a large part of the water out, and placed it into another bowl. Sprinkle the flower seeds into the mixture and gently stir them in. Again, squeeze more water out of the pulp mixture.
Place a screen you purchase for this or a spatter guard from cooking on an old towel. Make the seed paper Valentines on top of this screen.
Take a wad of the pulp and push it down flat inside the cookie cutter.
Gently pull the cookie cutter off and leave the Valentine on the screen. Continue this till all the pulp is gone.
Let the Valentines dry on the screen.
Once dry, use a couple spots of glue or some tape to stick the Valentines onto a sheet of construction paper cut in fourths (or print off the attached Valentine background shown above).
Write your message, something to do with growing. “I like how we have grown to be such good friends” or “My love for you keeps growing”.
Let your Valentine recipient know that they can plant the Valentine in a pot under ½” of soil and see their flower seeds grow!
