Watercolor.
Just because she has ventured onto drier terrain does not mean Petra has left behind the flowing wetness of watercolor. Her intent was to bring even more definition to the shapes beginning to emerge from within the paintings via thin layers of color. Additionally, the edges of the glued on shapes and the crevices of the textures in Franzi's layers of blue are hospitable places Petra's watercolor to pool gather and pool, creating thin lines and adding depth.
