As few as four or five people can make for a productive workshop, but you should decide in advance what your set minimum participation will be. These are best done with some type of desktop software, but if that isn't possible handwritten announcements will suffice. Check with the local high school to find out if they are willing to post announcements for you. Some schools will permit language instructors to make an announcement for you to their students. When approaching schools, be prepared to answer all their questions concerning what the objectives of the workshop will be, along with meeting times, location, and any fees or materials needed for the workshop.
Public libraries are generally very accommodating to literary projects.
Check with their activities director to find out if a meeting room can be arranged with the library, as well as to establish a convenient day and time for the sessions. Often, they will help market the workshop by announcing it in their bulletins or newsletters and posting an announcement in the library. Your workshop objectives should be clearly defined before your first meeting. If developing writing skills and the study of elements within poetry is the focus, give everyone who attends an outline of upcoming topics. On the other hand, if your workshop is more focused on reading and discussion of poetry, it may be beneficial to outline your sessions as you go along.
