I make homemade crocheted blankets and I want to put NFL team logos and names on them. I would like to display pictures of the finished blankets on sites like Face book in hopes of selling them to friends and family. I do not make more then a $30 profit from any one blanket and I will not be mass producing them. I am not a business, this is just a hobby I do from home in my spare time. How should I go about making this situation legal and not risking a lawsuit?
