How do the two sides of the wood seem different?

The two sides of the wood often differ in texture and color due to their exposure to different environmental conditions. One side may be smoother and lighter, having faced sunlight, while the other could be rougher and darker, shaded from direct light and moisture. Additionally, the side exposed to weather elements might show signs of wear or aging, contrasting with the more pristine appearance of the sheltered side. These variations highlight the impact of natural elements on the wood's surface.
