You can vary the look of the clusters by wrapping more times for larger clusters, and fewer times for smaller clusters. You can also wrap the yarn tightly or loose to change the look of the clusters.
To make clusters: k3, slip those 3 sts from right needle onto a cable or DPN (should be same size as needle used in project or smaller - a larger DPN can stretch your stitches); wrap working yarn counterclockwise around stitches six times, then slip those three stitches back to right needle.
