Wavy waves

You need:

1. white drawing sheet A4 size
2. markers
3. coloured paper for background
4. glue
5. scissors

Draw on a white sheet with pencil four wavy lines from left to right.

Then draw five wavy lines from top to bottom.

Draw a cross of slightly wavy lines in each square.

Choose three colours and colour the triangles: one colour for the bottom triangles of the squares, another colour for the left triangles and a third colour for the triangles on the right. The upper triangle in a square is always white. This is the foamy head of the wave!

Cut a slightly wavy line on the left, right and bottom of the drawing. Cut a strip of the upper triangles away. Paste the work 'wavy' on a coloured sheet.
