Yoori's work begins with the materials found in everyday moments. Write down things in writing or simple drawings that are too ordinary to be excessive, or moments captured in unexpected situations. In addition, when an idea of the material comes up or an image to be drawn is created, the collected records (sketch) are randomly combined and transferred to the screen. The material itself is drawn as a motif, or an image created through a single imagination of the material derived from it is also featured in the work. When the composition of the work is completed, the work is completed by focusing on the object itself rather than the deion of a specific situation with quite spontaneous brush strokes along with the consideration of color.
