Playground days

When I visited my grandchildren last weekend, we had a moment to investigate the local quilt shop for inspiration. 

Miss 3 and a half told me her favourite colour is pink, but she also likes purple and green and black! Sounds like a colour palette to me! 

I have some fabric on the design wall. Not a bad start but I need more pink! Lots more pink!

I have been looking through this book for inspiration: 

There is a cute pinwheel design that is called " playground days" which I am interested in. If the white were replaced by black and there were lits of pink and green and purple pinwheels I think it could be quite interesting.
