Start by cutting out circles about 1/2 inch in diameter from tissue paper. Set aside and cut a cardboard heart-whatever size/color you want.
Take a tissue paper circle and twirl it around the pencil's eraser.
After twirling, without taking the paper off your pencil, push it down into the glue so it sticks.
Cover the whole heart in little tissue paper poufs.
Tape the ends of a piece of string to the back of the heart.
