Making use of all those crocheted flowers

I have come up with a lovely little spring and summer scarf, it's like a daisy chain, I'm just doing a test one now and I will post pictures of the finished item, hopefully modelled by my lovely daughter.
I'm quite excited about it because I so love making the flowers, just need to decide whether to keep it all one colour or to do contrast colour centres to the flowers.
I will keep it all one colour for now, but I would appreciate some input as to whether people think it would look better with a contrast colour in the centre of the flower.
