Continue Vertical Plank Installation and Leveling

What happens here

After the initial vertical planks are in place, add more vertical dark gray composite planks, varying their heights and positions to create a dynamic, rhythmic pattern. Use a spirit level to ensure each plank is perfectly plumb before fastening it to the wall. This creates visual interest and prepares the structure for shelves.

Goal: Complete the vertical pattern of the wall, ensuring all planks are plumb.
