Wood is a natural material with variations in color, texture, and figure. These variations are influenced by the natural growing process, which includes sapwood (light), heartwood (dark), and minerals that the root system is exposed to. Consequently, doors will have natural grain and color variation between stile, rails, and panels. 
All dimensions prior to trimming.
