Recruiting for classes

I am teaching in 2 stores that have only had the Wilton classes for several years.  After 2 demos per store, I still have no folks signing up for the classes.  I have made fliers with dates/times and hung them in the yarn department.  I know it's the holiday time, but I am really interested in starting off well with the classes.  The store managers are supportive and realize that we may have to cancel empty classes or have very small classes to begin.Has anybody found any success with class recruitment?
