A violin maker wonders about the origin of a practice in his trade known as purfling, where a black and white line is inlaid into a tiny channel along the edge of the instrument. Martha traces the word back to the Latin filum, meaning “line” or “thread.” Purfling is also a practice in guitar-making, furniture-making, and embroidery, and it shares an etymological root with profile. A fun fact: purfling is also just “profiling” said with a mouth full of marshmallows. This is part of a complete episode.
