For this project, I decided I wanted to make an image of an ice cream cone with a cherry and sprinkles.  The basic shapes I used were lines, ellipses, and triangles.  I also used various stroke weights for different elements.  Some of the challenges I faced were getting the lines of the "cone" to appear in the crisscross pattern as shown.  I had to play around with the coordinates a bit but it became easier as I went along.  Another issue was how I wanted to create the "sprinkles".  At first I just made them as individual points with their own colors, but they weren't the correct shape, it was difficult to place them so they looked natural, and it was hard to keep track of each one if I wanted to target a specific one.  The solution to this was to make small lines and group them by color. Another issue was the sizing.  I had made the image too small at first, but that was corrected by using the scale() function and sizing up the background.
