Here's an advertising tip for Renfaire Organizers: It's getting to be that time of year. If you want to get exposure to non-Rennies, enter a troupe and/or float in some nearby Christmas parades. This would be more helpful, I imagine, for those who hold faires in the springtime but some people have long memories.
If you have a presence of different types of personas, you would appeal to more kinds of people. I guess pirates celebrate Christmas. I'm sure that Crusading knights do. Some archers do for sure. Do you have a flute or guitar player that can play carols?
You could also hand out flyers along the parade route. Don't bother with business cards. People stick them in their wallet then a drawer somewhere for a few years. Patrons need something to take up some bulk in their pocket or purse.
This will give you a good excuse to garb up. Huzzah!
