The knitting technique used to create large blocks of color is called intarsia.
Each color is worked with a separate ball of yarn, and the yarns are crossed at the color change to lock the sections together.
Tip: when working small motifs, wind off a small amount of yarn for each color area and let them hang loose at the back of your work. If the yarns get tangled, you can easily separate them if they are not attached to balls.
To make change colors in the middle of a row:
1. With the first color, knit up to the color change, then drop the first color.
2. Pick up the second color, crossing the yarn underneath the first color, and work the first stitch tightly.
3. Give the end of the old color a slight tug to lock the colors together, then continue knitting with the second color.
