Inquiry minds want to know (?only) if it is legal to purchase a used book and use the CD or to borrow from the library and use the CD? To me personally, I think, the book needs to be purchased by the user to have legal rights to copy the CD...and I would question if buying it used would be legal. To me, only if the author received her percentage on the sale of the book, would the book sale be legal. Just my two cents worth.
I was emailed an inquiry to buy the FWSQ book after we finished that journey, and I said "NO!!" I had made private notes in the book, and it would NOT be for sale. I respect the rights of the author and her hours of labor it took to publish the book too much to part with the book. It's willed to my grandchild with the quilt.
