Yes, I always develop a timeline for each event that I coordinate! I send these out to my clients and their vendors about a month out from their event date. This allows time for vendors to make any necessary adjustments so the final version of the timeline can be sent out two weeks prior to the wedding.
These timelines include details such as vendor arrival and set up times, a hair and makeup schedule for the bridal party, a photography timeline, the order of the processional, the ceremony outline, the order of special dances and song selections, the order of toasts, etc. Every detail of the day will be included in the timeline so that all of the vendors, family members and wedding party are on the same page on the day of the event to ensure the wedding day flows seamlessly.
