For the most parts, the main details such as the reservations of the venue for the ceremony [church or chapel or a particular venue] and reception, wedding gown and accessories [includes motif, design, where to buy, etc.], catering, budgeting, guest list, invitations, flowers, entourage, bridal car and salon services are always on the top of the list. Minor details such as wedding registry, gifts for the groomsmen and bridesmaids, name cards for the tables, wedding favors, thank you cards and many other small details come next. It is easier to have a wedding planning checklist because you'll be able to track everything, check which is missing from the list and forecast your budget. A wedding is huge investment and every penny counts, so a checklist also provides you a clear picture of how much you will need, how much you can save and how much you need to add if you were able to save for the honeymoon.
The item listed after the budget on the party planning checklist is usually your venue choice. If you are planning to have the party away from home the venue choice will cost money and will come out of your budget and a time will have to be arranged for decorations and so forth. If your party is going to be at home, and you have to hire a professional to come and clean some unwanted stains out of your rug the parties budget will be affected, making it an important listing in your checklist. Of course, if your home needs nothing besides some freshening up you may leave it off your list for now.
