Desperately Seeking Opines

I am flirting with the idea of starting an Etsy shop. Just a very small one mind you. I would like to sell my prints - the linocuts I have made. Most images are editions of ten or twenty and I thought to sell them for $20. I am wondering what you think. Is that a good price? Or better - does anyone know someone running an Etsy shop and is there a trick to generating traffic for and thus sales of your product?
