I've been making simple handmade greeting cards using my own artwork as well as store-bought embellishments and papers. (I also use fonts I've downloaded online, but only free ware fonts). I'm not making the money I used to and when a stranger brought to my attention that my cards were actually pretty good, i started thinking of selling these cards. I'm not sure how to go about this though. I dont want to get sued for using the embellishments, although the ideas are all my own. Also, if i'm going to sell them, how do i copyright my own work and get a business set up?
