The appearance of these rectangular designs is such, that they can very easily be made into frieze, repeating patterns, borders... Also, by deleting the lines along the edge, you can simplify (reduce) the designs, and by additional drawing, you can draw a similar but larger, more complex design. If you have a knack for drawing, these designs can serve you just as a quality idea and inspiration to draw your original rectangular geometric design. These two designs can be said to belong to the Op Art style; should you feel interested in modern art, geometry and optical illusions, we recommend that you study this artistic movement.
