Cut down a few sheets of plywood and use them for the horizontal planked walls, or on the floor........
Wood Plank Wall - she used pine planks rather than pallets making this project a WHOLE lot easier. Stained with dark walnut stain. LOVE.
Stamped concrete flooring.Very cool for a mudroom or bathroom. Polished concrete is a really great flooring solution to large open spaces. With a scattering of area rugs, lofts can get away with this. Also looks great in a basement is done well.
Wood accent wall from 8' and 6' fencing purchased cheaply at Lowes. They brushed each piece with a grey stain, then white washed over each one. They used a different white wash ratio with each board to make each slightly unique ~ working the brush against the grain. After they were dry, they distressed additional boards using a chain and hammer.
Need a feature wall or a focal point? Buy 4 x 4 lumber, and slice into 3/4" - 1" pieces. Use liquid nails to affix to your wall. Stain, paint, urethane or do nothing at all.
