As hyacinth was growing and changing almost hour by the hour I made a series of prints using stencils, masks, gouache, and a few accents with colored pencils for details. One of the stencils looked interesting by itself and ended up glued to the back of another sketch at the end (last image in this post).
These are sketches of the process of growing. They are done a little bit at a time time with the big shapes pre-painted based on one stage of the flower development and then some texture added with all sorts of tools. And after the background dried, I would sit down to look and see the change that happened in the plant in that time and add details.
