Thanks for the reply Messman, I understand what you are saying, for example I can take one of your patterns from the pattern library, lets choose Hitch'n A Ride and I can change some of the elements of this pattern and cut it out until the cows come home and I can even show it off online but I can't return the modified pattern to the library or distribute it for others to use.
Lets get back to this pattern I am doing ,the front layer of this pattern is an elephant which is a free pattern and I can do the same as I have mentioned above and that is place a frame around it extend the grass to the edge of the frame and I can cut it out as much as I want but as soon as I add it to the layered pattern and cut that out I violate the pattern copyright law, that is correct isn't it ??
Don't worry my brain is already crazy as it is, this has actually taken me to a new level of thinking as I in a sense thought that a free pattern was a free pattern that I could do as I pleased with it.
