ZIG ZAG CARD
To make the card, fold a long rectangle of thick paper, the front part should be narrow than
the back part.
• Turn the paper over, Then, fold back the right hand section so that the new fold lines up with
the back edge of the card.
• The front section should be about half of the width of the card. If it’s wider, draw a pencil line
down the card and cut along it.
• To make the heart decorations, fold a piece of thick paper in half. Draw half a heart against
the fold, then cut it out.
• Open out the heart. Lay it on a piece of pink paper and draw around it. Then draw it twice
more on other piece of paper.
• Cut out hearts. Then cut out another smaller heart from thick paper. Draw around it three
times and cut out the shapes.
• Glue small heart into each big heart. Then, glue the big hearts along the edge on the front of
the card.
• Brush lots of dots of white glue around the edges of hearts and press on sequins. Then, leave
the glue to dry.
• You can decorate a card with flowers and with your own creativity.
