Hi, folks, I'm doing some trim work on my old house and I have discovered a big ol' HOLE in a wooden panel. I'm guessing it was supposed to be a cat door or something, but it's not cut out nice and square so I can easily patch it, it's very ragged and irregular, though vaguely square- shaped, about 8 inches square.
Any thoughts on how to best cut a little panel to fit in there?
Thanks!
