Here are some examples of things that can be done to hats depending on how you work the colors. The red and black hats are done on round looms working in the round. One is showing bands of color, alternating the colors and a wide strip of color along with a narrow. The other red and black is a spiral pattern.

Now the blue and black hat shows what happens to the stitches when you work the flat method of ewraps on a straight rake. See how the colors from one row slant differently then the next row. Kind of neat huh.
