I snagged this image from the Courtney Callahan Paper Blog (stationery designer!) - I LOVE this idea for a printed, elegant seating chart. There are so many interesting ways to display your escort cards and seating assignments... see below what I design for our wedding.
It is kinda funny - I designed this for our guests to take their card off of the board, but everyone just looked at their assignment and left the card! Either way, it worked great.
What will you be creating for your seating assignments?
