I'm replacing our skinny wood trim with some chunky white trim gradually room by room. I'm doing the entry now, which has beadboard that has to stay, so I'm working with it. I've run into a problem because the beadboard is behind the floor trim so it sticks out slightly past the trim around the door. What do I do here?

For reference, here's how the other rooms are done:

Also, the corner where the beadboard ends is right next to another door. The older trim was skinnier so they didn't run into each other. Is there a better way to arrange them than this?

Thanks for any advice!
