One of the most important things you can do to prepare for open studios is to make it easy for people to find your studio. A sign out in front of your building is good. A few more on the corner or at the nearest cross streets are better.
In past years BOS has had signs made and distributed them throughout town. With more artists participating every year, it will not be possible to continue doing this. Not only is the expense prohibitive, it is time consuming as well. At most open studios across the country it is generally seen as the job of the artist to make their own signs.
Below is a pfd with the BOS logo for you to download. Print it out, post it wherever it needs to go to be seen.
