Hi Amia,
It wasn't quite the same question but see my answer in this thread.

People still say to me that mine was the most fun, relaxed wedding they had ever been to, and I wouldn't do it any differently if I did it again now.
My cousin and my siter both did their weddings intimate and cheaply too. Cousin had a cream and gold theme and used Christmas decorations bought in the January sales and you would never have known, the room looked stunning and not in the least 'Christmasy'
I think the key to fun and keeping the cost down is keep it simple and keep it intimate. Genuinely close friends and family only, that way it doesn't matter what you do your guest will have a great time.
Friend of mine went to a 'second time wedding' where there were quite a few little girls, daughters, cousins etc. they wanted a fun, informal wedding and decided rather than choose a couple of bridesmaids they'd buy them all a fairy out fit and they went down the aisle at local registry office accompanied by 12 fairies!!!
