and try your hand on it. Apply the four steps previously described:
- Put a crossing at the middle of each edge.
- Connect the bits with one another using the maze.
- Emphasize the over/under feature with the guide.
- Widen the road, first the bridges then each side of the road.
Remember, each crossing occurs at the middle of an edge and each edge bears a crossing.
One edge = one crossing
And to connect the bits, repeat:
Follow the wall, turn the corner, follow the wall.
If you don’t succeed the first time, don’t despair and have a peep at the answers.
