If you are just starting out, it helps to have a good variety of different types of items. Once you are established at a show, people will come back every year looking for you and what you have new to offer. So you usually can't just do one thing and keep doing it over and over, unless it is something that is used up like candles or soaps or lotions and potions that people find they really like and keep coming back for more. But you still have to have something new and different every so often even in those.
