I used my daughter’s crayons, a different color for each main character. One end of the wallpaper was the beginning of the story, and the other end was the end, and then there was all that middle part, which was the middle. And the blue line met the red line and then the yellow line, and then the yellow line stopped because the character represented by the yellow line was dead. And so on. The destruction of Dresden was represented by a vertical band of orange cross-hatching, and all the lines that were still alive passed through it, came out the other side.
