Every quilting book I checked said no reproduction at all, or no reproduction except for the exclusive use of the retail purchaser. Copying from a book is just like copying a video. It's stealing from the person who owns the rights to reproduce and sell that article. The same goes for copying quilt patterns that are sold separately. By buying it you have the right to use the pattern, but not to make copies to give away or sell. You can, however, give away or sell the original pattern, provided you don't keep any copies.
Now the patterns in magazines - that's another story, and I don't know the answer.
