I discovered this brick, stone and wood grain wall paneling in Houz Depot last weekend by Klaus Decor. Called FashionWall, it has a variety of designs. Get rustic, get sleek designs, with time and cost savings because it is easy to apply (DIY) besides you can achieve the same look and texture without needing to pile your porch high with loose materials. In fact, it's environmentally friendly material as well mold resistant, giving you peace of mind that it is a long term investment.
Go to the website to download their complete installation instructions as well view the video tutorial for better understanding. Can't go wrong here :)
