OK. So how about this. What if you wanted to sell purses on a forum like etsy. If you were to add in the price of a pattern for each purse sold, and purchase such pattern for each item sold (I know, kind of far fetched), would that be legal? Is the copyright ensuring the person gets paid, and that's it? I've always been fascinated with the boutique sales and etsy shops, but haven't participated in any because I am very aware of infringement issues.
