For this exercise I decided to use pennies, dimes and paper clips. In the first photo I made a pattern by having the pennies and dimes go down a vertical row. They go down one at a time with pennies first then dimes, creating a pattern with different use of coins. In the second photo, I decided to use red paper clips to break the pattern and because the color red helps make them stand out in the black background instead of blending in.
good idea to use the black background.
