I would very surprized if I am the only one that has done this. About 2 years ago I built a cradle out of walnut. When I joined the boards together I did not make note of where the biscuits were. Yes, you guessed it. When I cut the design out I cut right through a biscuit where it will show up like a sore thumb, white biscuit on dark walnut. What to do, so I made a small strip of walnut and glued it over the bad place, one on both sides so they both look the same. Later my wife, and others, said ‘I like the decorative strip you added’.
