Posted on April 12, 2019 by BrookeWallpaper Patterns I was surprised at how easy I found wallpaper patterns just around my house. Above is a wallpaper pattern that is on my shower curtain. Rotation order is 2, there are reflections in both directions, and I believe all rotation centers are on mirror lines. This wallpaper pattern is pmm. This wallpaper pattern was found on a tissue box. Rotation order is 4, there is a reflection, and there are not mirror lines intersecting at 45 degrees. This wallpaper pattern is p4g.
