Fill each spray bottle half way with a different watercolour. Fill each bottle the rest of the way with water. Put each lid back on securely and slowly rotate each bottle to mix the watercolour and water.
Spray a few pieces of diffusing paper with all of the different watercolours. Watch as the colours bleed into each other. Allow to dry.
Using your decorated diffusing paper carefully cut out 18 ovals (4 x 5cm) and 18 ovals (3 x 4cm). These will be used to create the petals for the flower.
To create petals, hold the oval with the short side toward you. Fold the left hand side diagonally toward the centre. Fold the right hand side diagonally toward the centre. Secure with glue and allow to dry.
Cut a circle from the decorated diffusing paper (10cm diameter), this will be a base for the flower. Place the largest petals around the circle. Attach with glue.
Layer the smaller petals over the large petals making sure they are off-centred with the large petals. Attach with glue.
To create the centre of the flower cut a smaller circle from diffusing paper. Place the circle in the centre of the flower. Attach with glue.
