I was at a quilt shop awhile back and they were selling the free patterns that companies had sent to them. There was a $2.00 sticker on it and it stated on the pattern that it was free! I did point that out to the owner. No telling how many free patterns they had sold.
Catmcclure, I agree that when you sell a pattern out of a magazine, it is not a copyright infringement. If it was a copy of the pattern, that's entirely different.
