Just a quick one...

 Ok so this isn't strictly a complete DIY decoration but just a quick, simple and cheap way of customising your wedding decorations.  The white hearts were about £1.20 each from ebay and the foam flowers (I put a pink one on one side and a white one on the other side) were around £2 for a bag - another bargain decoration!!

Apologies that the pic's aren't too brilliant but just to give you an idea.....
