I think the longer you have to plan the more majical the day will be.
If you plan now, then you will be able to get what you want.
If you plan early then you dont have to worry closer to the day.
I started to plan a year in advance and i'm glad I did as its just a walk in the park now.
so plan as soon as you can. Stuff like booking the hall, church, picking invitations, place setting or get the bridal bible, it has a check list in it that tells you what to get.
