Thanks Dunster but that's not it. I have the Twisted Log Cabin book. This was a very striking 3D block that looked liked you could fall right in the center. I had pictures but they were removed. They are everywhere online. Google 3D log cabin block. I can't find a pattern though. All I know is it is made with wedges.
