A memorable wedding
Having a memorable wedding does not depend on the budget. You can let your creativity run and make your wedding memorable. 
Make it different from all other traditional ones. This way you and your guests will remember for a long time to come. If you have enough budget, then it is a good idea to hire a wedding planner. The wedding planner is responsible for ensuring that your flowers are fresh and the venue looks beautiful and the service is faultless. The planners are available at various price ranges. You can choose the one that suits you best.
Choose a theme that will be different from the common ones. You need to ensure that the entire decorations match with the theme of the venue. The flowers, the table cloth, the bouquets and similar ones need to match with the theme. The menu should take care of the preferences of majority of the guests. Try to make the return gift and thank you note unique. It need not be too expensive. Just make sure you make it a little different.
