I'm repeating myself (that's what happens when you run round in circles).... but my understanding is the quilt Jane Stickle made cannot be copyrighted because it's too old. So the blocks that make it up are public domain, meaning our tutorials on putting them together are legal.
What is copyrighted is the software, obviously, Brenda's book, and the name "Dear Jane".
I can understand putting printed files from the software on here could be a breach of the software terms. And we shouldn't be referring to "Dear Jane" without the appropriate copyright message, whatever that is.
But the rest of what we are doing is perfectly fine!!
