Faux wood planks and beams! Very budget friendly and come in a lot of different styles and colors. They can look extremely modern and very rustic depending on use. The upside to this material is that it's very easy to create any look you want. The install is much cheaper due to lighter material used to make faux wood. It is typically a variation of styrofoam put into molds then painted. In the right artist's hands and at a height of at least 10 ft they can be quite convincing even to a keen observer. Buyer beware though, as not all faux wood is created equal. Some can be convincingly real while other products can look cheap and cheesy! That's where the artisan installing the product can be of great value.
