Hey people, chill! No one has ever, to my knowledge, claimed the copyright to the design of a block that they did not in fact invent. The written instructions are all that are copyrighted - the words on the page, together with any original art work or photographs. Not the method of construction, not the block, just that particular set of words and art work. Don't complain about a problem that doesn't exist.
Example: I wrote a pattern for the quilt in my avatar. I didn't invent the diamond log cabin design, and never claimed to. Part of my setting may be original to me, but I don't even know that for sure. But my pattern is copyright protected, because it is original. I put together the words and the pictures. That can't be legally copied by someone else, but anyone can make a quilt like mine, and they can do it with or without my pattern, with or without my methods of construction.
