Develop guest list—This obviously goes hand-in-hand with the above task. Given the time frame needed for the invitations, you'll need to have your guest list complete by 6-8 weeks before the wedding day. Start with a number limit that you feel comfortable with, and make an "A list", "B list" and "C list" (parents can do the same with their list, or simply give you a list of the people they want to invite, and you can negotiate as you go along). The "A list" is those people who will unquestionably be invited, the "B" is for people that you would really like to be there, but could "cut" if absolutely necessary, and "C" might be for co-workers, acquaintances, etc, whom you could leave off the final list if you exceed your target number. Typically, you can expect about 80-90 percent of invitees to actually attend your wedding, but if there's a "Murphy's Law of weddings", it may apply here, and you may have a higher percentage of attendees, so plan accordingly.
