Is there a reason you can't just turn the outside to the inside? Are they miter cut? (can't tell from the photo, sorry) If so, is there enough meat to miter cut them again the right direction so you could turn them around? Could you cut a piece that would fit at the edges that would in effect make the miter cut disappear. or even cut the miter off and use a cut piece as the new corner?...could be the same wood or a contrasting wood, or the same wood stained a different color. If not, I'd call them my templates, throw the pine one away, and start over. Jim.
