The pattern is the property of the designer, it is copyright protected. It makes no difference if it was a free pattern, it was only a free pattern on the Free4All site. That's the way it is with all these sites, we get patterns for free because we are members. And as members, we get the right to use the patterns, but they still belong to the designers to do what they want. Take Don, Don @ Old Crow Scrollworks, he is generous enough to share his patterns with us for free. But he also has a site that he sells them from, so why would he want you to give his pattern away? Don is a nice enough guy, that he probably wouldn't mind. But before you shared one of his patterns to a person who isn't a member here, you should contact him and ask.
