Step 1: Take some rolls of crepe paper.
Step 2: Cut them into strips (of the same size), fold them and start cutting fringe about 3/4 of the way. Then unfold them.
Step 3 & 4: Attach the fringe pieces to the heart with glue starting with the lowest part of the cardboard.
Stept 5 & 6: Keep going until you cover all the cardboard surface.
Step 7: Fold over the last strip and glue it behind the cardboard.
Step 8: Now cut the excess crepe paper bits off the sides to create an even heart shape.
