Seating Chart - help

When I was planning my wedding I was addicted to LIW and everyone was soo helpful. A friend was asking about a Seating Chart for their wedding.

I was thinking of making one for them BUT how to you print something that big? Did anyone use a seating chart at their wedding and do you know where/how it was printed? It obv. needs to be big enough for everyone to see and read.


Thanks in advance.
