The wall paneling is a solid feature! Each box contained 2 dark planks, 2 light planks and 1 gray. Their square footage calculation for boxes needed would have been correct, but I ended up having to purchase one more box because of stud locations on my wall and the cuts I needed to make. Once I figured out the logistics of stud locations, lengths of boards with no joints overlapping and color layout, the install was fast. I used a 15 gauge nail gun with 2" long nails. Absolutely beautiful for our updated guest room!
