3 Increase the repeat size to give yourself room to work. You can do that by editing the control path. While you are at it, make the pattern into half-drop by dragging the right side of the control path down half-way.
4 Add a few replicas of the original flower image. Rotate, reflect, and move the replicas around to create an organic look. Notice that the pattern changes as you work with replicas so you see your design in repeat at all steps.
