Trace the small hearts and strips on a paper, the body (oval shape) on a paper, the big hearts (outer wings) on the third colored paper and the small ones on a different shade of the similar colored paper. Cut out the traced patterns nicely.

Glue the small hearts on either ends of each small strip. Stick the medium sized hearts on the big ones.

Using the glue, stick the heart antennas on the top side of the body base (oval shaped paper). Stick them on the backside keeping the hearts facing up.

Glue the heart wing patterns on both sides of the body base. 

Stick the googly eyes on the oval shaped part and use a sharpie to draw the other details of the butterfly paper craft.
