Tear Paper - Let your kids go to town tearing paper into little pieces and place them into a bowl. After you have all of your paper torn up, it's time to add your warm water.Add Warm Water (and food coloring)- If you used colored paper you won't need food coloring and can just add your warm water. If you used white paper mix your warm water with the food coloring before adding to the paper. I used the McCormick neon pink one.Let soak - Let your paper sit in the water for a couple of hours, maybe even overnight.
Blend paper into pulp - Then use a hand mixer to blend the paper into a pulp. You can see that my mixture had a sheet of paper that had some kind of coating on one side so it didn't blend into the pulp mixture. In the long run, though it looked really good in the project so I left it in there.Drain water - Drain any excess water off the mixture, but make sure you leave it moist. Don't squeeze any water out because you need it to make it spreadable.Sprinkle seeds into mix - Sprinkle your flower seeds into the pulp and blend well so that they are all throughout. Do not use the mixer or blender to do this because you could damage the seeds.
Prep screen - I used a splatter screen for this project but you can use a window screen or buy some screen from your local hardware store. Place your screen on top of a cooling rack with a paper towel underneath. As you mold the shapes it will start to leak through the screen.
Shape mixture - Hold your cookie-cutter tightly against the screen. Put a spoonful of paper pulp mixture into the shape and use the spoon to push and move it to the sides. Get it as even as you can. Make sure your shape isn't too thin because when it dries it will get smaller, making it very brittle and hard to remove from your screen.
Let dry - After you have a few placed on your screen you can place them out in the sun to dry. I made these in winter so I didn't have much sun, I ended up placing a box fan over them to speed up the process.
Carefully remove from the screen - Once they were dry I had to bend the screen just to get them off. I suggest peeling them off yourself, just to make sure none of them get torn.
Attach to Valentine's card - After we were done with our hearts, I created the valentines that we would give to her friends. You can download the printable HERE.
