Dear Moondragon,
Once you get it into a graph, the dual and the primal behave exactly the same: put a cross at the middle of each edge; to connect the threads follow the wall, turn at the corner, follow the wall; to decide the over/under, use the guide...
Everything is the same. Except that the dual is boxed in walls, that’s the beauty of it. That means that boundary edges are walls, don’t put crossings there.
Keep it up! Christian
