i truly believe that if you are in the business of making items for sale from licensed fabrics, it would serve you well to get professional business advice beforehand (i.e. legal, financial). i think it is naive to do otherwise. i made and sold children's clothing for years, most of it was made from my own designs or some commercial patterns that i suffiently changed from the original that the final design no longer resembled the pattern. i also had a financial service business that i ran for 15 years. i made sure that i got legal advice, used the proper content labels in my clothing, kept myself abreast of the laws that would affect me and carried any of the necessary insurances that i needed to attempt to guard myself against lawsuits. believe me that still did not prevent me from receiving a lawsuit threat. i still had to prepare myself for the lawsuit and did my research on the law and the limit of my responsibility.
you cannot stop lawsuits no matter what, not in this litigious society. someone could sue you for not making full disclosure of the materials you use in your items, for using a copyrighted pattern or fabric in your design for sell, for using a protected image without written authorization, etc. my best advice is if you are making money by selling handmade items, get the proper legal advice needed. pay the legal fees to get the advice in writing, know the laws and your responsibility or exposure under those laws and be prepared if a lawsuit comes your way.
think if all of the people (students, homemakers, etc) that were sued by the music industry for having downloaded music. the music industry knew that many of these people did not have the money to fight them but that did not stop them from suing. virtually all of the people lost in these suits and had to pay up regardless of ability to pay. know that it can happen and it may happen. i believe in being informed before i start any money making venture.
when dealing with the public, there are government public safety protections out there they you as the seller need to be aware of. content labeling is one of them. what's copyrighted is another. just do your best to be informed.
