This shell design couldn’t have been carved without new v-shaped gouge I recently ordered from Japan. I depend heavily on general craft knife when carving stamps but always had difficulty carving hairlines. I used to avoid hairlines as much as possible when I designed images for new stamps, but not anymore! I can carve 4 hairlines within 1/8” with the gouge.
The design look simple but I am personally very satisfied with the result.
Pastel colors inks such as light blue or light yellow would go well with the stamp.
