If you plan to have any kind of assigned seating at your reception, you might want to refer to yesterday's post to help get you started.
The January 2011 issue of Martha Stewart Weddings gives helpful advice on how to save time when assigning your guests to tables.
You can place round circles on construction paper or card stock and use the thin strip sticky notes. Write your guests' names on the sticky strips and start placing them at tables. If you need to make a change, simply pick up the sticky note and place them at a new table.
You can then create a final "master" sheet when you have it finalized!
