I was cutting baseboard trim wrong for a decade until a guy in line at the lumber yard said one thing.
I always just butted the ends together square, thinking that was the 'clean' look. Last Tuesday, I was picking up some pine for a job in my garage and the guy behind me saw my cart. He said, 'You know, a simple scarf joint hides way better when the wood moves.' I went home, cut a 45 degree angle on the ends of two pieces, and glued them. The seam is almost invisible now, even after the heat came on. Anyone have a better trick for long runs where you can't get a single piece?
