This pattern is worked in continuous rounds unless otherwise noted. Use a stitch marker or piece of yarn to mark your place. It is best to watch how your colors appear as you work so that connecting stitches look appropriate. Background image credit: CT Cooper/Wikimedia Commons.

There is some great detailing by using back post stitches as well as slip stitching and using the back loops.
