It was a two-part stencil, which meant I had to do each set in stages, letting one part dry before putting on the second stencil to do the other parts of the image. I wanted a more realistic effect than solid colors would give me, so I used layers of green and yellow for the turtles, and I used several shades of green on the plants. I used both orange and yellow for the coral. I only used blue for the bubbles. Overall, I think it turned out rather well. However, adding all the additional color meant that what might have been a 2-hour job took me closer to 9 hours.
