We did it together, but I actually liked hers better than mine.
There are just 3 simple steps:
1. Sponge on watered down blue (the tutorial said water colours but we used watery poster paints)
2. Use a playdough cutting wheel to paint on green stripes
3. Use a cotton tip to paint coloured flower dots on.
A lovely way to experiment with different ways of applying paint, and cute results.
