I just saw that Electric Quilt sells Dear Jane software that is a stand alone software. That should mean you don't need Electric Quilt to use it. It looks like it might be worth buying. Of course, I have EQ7 and EQ6, so I could just use that. I just don't see anywhere what the size of the blocks are to be.
