A few questions

I have a few questions I would love feedback on. I am debating on teaching at Costume College next year. I don't want to offer something no one is interested in. I would also like to do it as anxiety free as possible.

For anyone who's attends Costume College would you be interested in a how to make leek buttons class. I know how and Can show how to make the death head and checkerboard right now. If I go ahead with it I wouldn't be opposed to learning more.

To anyone who has taught. Is it an easy process? How was the experience, the good and the bad? Did you have problems with people being snarky? Do you choose if your class is limited or not? Any pros or cons for limited vs unlimited?
Those are the only questions I can think of... Like I said any feedback is highly appreciated and feel free to pm me if you don't want to make something public.
