The flooring is 1 x 8 pine boards that we stained and sealed. It was the most reasonable solution we could come up with...I really wanted it to look like Grandpa was milling rough cut lumber out in the barn and sending it in for the floor. I left the knots and the wood took the stain differently in spots so there is some variation in the color but that was exactly the look I wanted. I really like it, it is super easy to keep clean and to put it bluntly it was cheap...lol
