I think it is best to practice drawing with the kistka before going near a reed, to learn the technique. Wax comes out most easily if you hold the tool perpendicular to the surface.Before using the tool on each reed, I always draw a line on a plate first (never tried a paper plate) to make sure that a big blob doesn’t come out first! None of the videos warns you about that!
