In a quandary!

I don't know what to do. We are coming to the end of this term's classes and there is going to be a shortage of students for the summer term. In fact we will barely make the room hire money which means I will be teaching for next to nothing. Do I do this as a labour of love because there is every possibility that it will pick up for the winter term or do I call it a day and stop teaching? I can always advertise again for the winter sessions. I do enjoy teaching but do I really want all the work of planning classes for very little in return. There is a core element of students whom I really don't want to let down but on the other hand I could be using my time more productively. I really don't know what to do. The summer is always a difficult time because people go on holiday, have gardens to tend and just like to be free to do what ever and not tied down to a class. I can understand this! I suppose in the back of my mind is the fear that if I get off the track I won't be able to get back on. Should I perhaps just run one class a month for the next six months and see how this goes? Make it more of a group than a class? I shall have to discuss it with those students who are keen to continue but I don't know what to offer them for the best. These things are sent to try us and they do. Not forgetting that I actually sell a fair amount of fabric at class! Always an important point to remember! Though with less students and a recession that too could go down. I need help and advice!
