I saw a picture either on the internet or in a magazine (can't remember) of a centrepiece which just consisted of 3 Gerbera daises in a vase. It looked really nice so today I got 3 flowers to try it out.
It looks really clean and simple. The room that our wedding reception will be held in has a blue and gold carpet, ivory tablecloths and chair covers and gold ties on the chairs, so I think the yellow would be really nice.
Plus, it would be really quick and easy to do the arrangements, and not very expensive!
