If it's a bowl made from wood that isn't very spectacular anyway, I'd be very tempted to just use it for experimentation......practice cuts and finish techniques, etc.
However, this very thing happened to me this past year on a bowl that I'd put quite a bit of effort in. It was a very nice bowl......a tribute bowl for the three daughters of a friend of mine. Darn, if I didn't break through the bottom.....while doing the foot. The bowl was finished, otherwise. I sure hated to lose this one.
Anyway, I took a piece of scrap wood from the pile, and decided to try and save it......it was worth a try......what the hell, nothing ventured, nothing gained.....so, they say!
The bowl turned out pretty good......and, was presented to my friend, who really appreciated it. I told him about the mistake, but it didn't seem to make any difference. This bowl is now in his home.....a family memento.
......might as well give the plug idea a shot! Who knows......if it was destined for the scrap pile anyway.....you've got nothing to lose.
