The checklist is about to be hammered with information and the reason for this is you're about to create your guest list. Here you should write out the invitees names, phone numbers and addresses. You will be needing this information for the invitations and it makes it much easier than trying to look through your address book and try and remember who was invited, what their numbers are and where they live. The menu should be added once you have completed the above. Now you will have a clear idea as to what you need and how much. List the items you need, then check them off the list once purchased, while also keeping track of prices. The same goes for decorations. The information listed above should help prevent problems created by trying to 'wing it'. If not, there is plenty of available information out there, you just have to know where to look. Good luck on your up and coming party and have a great time.
Sure it's okay that you'll hire someone and pay him/her to tackle all the details and issues; but many couples have made this costly mistake of leaving all the work to the coordinator. Not that the coordinator cannot handle it or that he/she cannot be trusted; it's just that it's not reason enough to let someone handle everything. It is ideal that you and your wedding coordinator have each a copy of your wedding checklist where you can tally each month or every 2 weeks as things progress. Yes, it is tedious and it could bring stress once in a while, but you've got to be always on top of the situation because it is your wedding. You need to have an understanding with your coordinator regarding the updates and tallying of details in order to ensure that every bit of detail, big or small, is being tackled and accomplished as needed.
