Harpsichord keys are covered in two pieces instead of the one piece plastic coverings now used on pianos. The front piece is called the head and covers the front part of the key up to the line denoting the beginning of the sharps (line JK). The rear piece is called the tail and covers the rest of the key.

A decision needs to be made as to the overhang of the head key cover. If you prefer the overhang, make the head keycovering 1 7/16” [36.5 mm] long. If not, make the key covering the standard 1 3/8” [34.9 mm]. The heads and tails are 1/8" [3mm] thick.
