Can you make beautiful and educational PowerPoint presentations with your art, that teachers can use in class?
I have posted about 10 different "worksheets" on TeachersPayTeachers.com. One of them actually keeps selling pretty regularly, but there isn't much markup on a worksheet so I only make about $10 a year on it.
However, if you look at their "bestsellers" in each subject area or category, they are almost always PowerPoint presentations. Look at few of those and see if you can come up with PowerPoints teachers will use in class. You can easily charge $5 to $6 each, you make it once, and it sells over and over.
Good idea, Vicki. Must look into that.
I haven't had much experience with Etsy, but I have heard some problems about it from sellers on it. For instance the checkout system, where customers are redirected to a blank page instead of to Paypal to complete the transaction. You might be better off with your own website using a Paypal shopping cart.
