1. Tear about 8 sheets of newspaper (lengthwise will be the easiest direction) into 1" strips. Cut those strips into little 1/2" bits and place in a large bowl. Cover with hot water and let soak for 24 hours.
2. The paper will start to look like a pulp. Work it through your fingers, tearing up any large lumps so that it looks like gray oatmeal. When the lumps are gone, take a large handful of pulp and squeeze out all the extra water.
3. Working the pulp in your hands, add white glue to the mixture at about a ratio of about 1 unit of glue to 4 units of pulp. Form a ball, place it on wax paper and press to form a flat heart that is at least 1" thick. Let dry for several hours or until it starts to harden. When you can pick up the heart, wrap it with a length of string, pulling firmly to make indentations. Tuck the ends into the back.
5. When the heart is dry, paint the entire shape with a thick layer of white acrylic paint. Let dry and then paint with a thick layer of red paint. Let dry and have fun experimenting with smudges that emphasis the texture of your heart. I added some glitter paint for a final touch. A spray of a glossy sealer would be a good idea to finish off your project.
