Start by tearing green paper into small pieces. Glue them randomly onto the blue paper cup. Draw a heart onto red paper and cut it out and glue onto the paper cup.
Cut 8 pieces of the crepe streamer of the same length: 4 green and 4 blue. Glue the streamer at the bottom of the paper cup, on the inside.
Glue first the green crepe steamers followed by the blue streamers.
Use a pencil to punch two holes at the top of the paper cup, one on each side of the cup.
Thread a yarn strand through the holes and tie the two ends together.
