It seems I can almost never get any displacements I touch to sew. The command might as well be magic to me. Even worse, at the moment I'm in a tight spot. I've got this panel on my zeppelin that refuses to join with its neighbors. If it can't be joined, I might as well just delete most of the map and start over, because it's all one big round displacement blob and it needs to be seamless. So can I make this sew itself? If not, is there any way to force it to? Like, the hammer equivalent of violently hammering two pieces together that almost fit but not quite.
