Appreciate your input on perfecting the corner cut. Thanks

If you want a perfect joint, make a coped joint rather than a 45 degree
miter. Use a coping saw to rough it out, and sandpaper wrapped around a
dowel to shape it to a perfect fit. It shouldn't take much sanding because
a coping saw cuts pretty fine, and quarterround is an easy detail shape to
cope.
