Wall treatment

Submitted to Community Café

I've done a search here with no luck. I'm getting ready to paint my walls gray throughout my house. My style is Farmhouse and my home is small. I'm looking for ideas in the area of chair rail but not exactly. I don't like to follow rules exactly so I'm looking for maybe unusual ideas for wood on my walls. I'm also waiting on a tree stencil to come in and will be putting a raised plaster 6' tree on my living room wall.
