I used to write books with directions and everything had a copyright along with a warning that any woodworking injury that resulted from using this book for other than a guide was not my fault. The bottom line is that if someone wants to sue you over a hangnail they can and there is likely a lawyer that will take the case. I get why artists and others who make their living designing and selling patterns need a copyright to save them from gross exploitation, but I always thought those "warnings" were mostly created to make the person on the end of the finial purchase and possible production to think about some form of ethical behavior. I also get why copyright laws are so complicated...it creates jobs within their profession to just enforce the laws and that creates job security, others to teach those laws and so on. I think we all know that copying something from someone else and handing it out, or even worse claiming it as our own is intrinsically wrong, even rotating a block and then trying to sell the pattern is more than just a "dicey" idea. Use this as a guide....if you have doubts then don't, if you buy something with the intent to distribute and it is other than M&M's then don't, if you make your living selling quilts... I believe designer's already know and intrinsically accept this is part of their doing business and just as long as you do not have a sweat shop cranking out dozens, you are likely not ever going to see a quilt police person at your door. Yes, we have certainly become a litigious society and we all should act responsibly...the one thing I am grateful about is that the seething anger that seems to have invaded our roads and much of society has not become rampant in quilting and hopefully "quilt rage" will never makes the national news
