First off I think the issue with Emily is a cease and desist letter not a lawsuit.
I got a cease and desist years ago from Precious Moments telling me I had 48 hours to disable my listing with an item made from their fabric. When I sent them the information from the lawsuit they had lost in 1996 I never heard another world.
There is a lot of misinformation. I've been told by the clerks at Hancocks and JoAnns that I can't use licensed fabric to make items. I quote federal law, they tell me they have a memo from corporate.
As an many areas in life people need to be armed with the facts.
Who threatened the seller? Was it verbal, was it written, was it a cease and desist from a law firm? Not very many facts here.
