WallpaperCraft (Stairs!) adds stair variants to opaque, non-luminous Wallpapercraft blocks. As such, it both an add-on to, and dependant of, Wallpapercraft - A Fresh Roll.
As an add-on to Wallpapercraft, the textures remain those originally created by oliviaoliviasson.
- 1.14.4 and later versions can be found on CurseForge - Wallpapercraft: A Fresh Roll (Stairs!)
Found a bug with the 1.14.4 (or later) version? Let me know in as much detail as possible on the Issue Tracker.
