Draw a heart on a piece of cardboard and cut it out. Trace the heart several times on the drawing sheet. Hearts should overlap. Trace the heart also on the edged of the sheet. Draw smaller hearts within the traced ones; be sure there is about half cm space between the two lines.
Draw and erase the the pencil lines of the overlapping hearts as if they weave together: below - above - below - above.
Colour the hearts between the double lines with oil pastels. Paint the sheet with diluted watercolour paint and leave the work to dry. Trace the oil pastel harts on both sides with coloured pencils. Paste the artwork on a coloured sheet and finish the hearts on the frame, using a silver metallic gel pen or marker.
