I did this sometime back, now that I have an exclusive design blog, thought will publish it here.
Thankfully I had two wine bottles with a slight height difference to start with. I feel Jerberas and Lilies look the best on tall wine bottles. I just bought few Jerberas and few extra tiny bushy flowers to go with it. I randomly filled it and just tied a satin bow around the neck of the bottles to break the monotony of bottle colour. It looked nice.
See it for yourself.
