That's a pain. So you can start on one wall, and by the time you circle around the room, the pattern is off? It doesn't seem like there is actually a way to make that work, if the walls/room aren't perfectly square.Haha. All good. Under that window was probably one of the last pieces and had to be overlapped to match the pattern. I'm pretty sure I was at the end of my patience by this time. I was so focused on keeping the pattern "in tact", that keeping it level under that window never even crossed my mind. It was however very level across the ceiling line and the rest of the wainscot. So cut me a little slack! 😅 🙏. I am glad you pointed that out though.
