I don't have a pattern. What I did is chose four different neutral background colors and cut them in 8 1/2 blocks. Then I used fat quarters of different colors and cut each one into 3 different size circles. On each neutral block I put a large circle and sewed 1/4 inch from raw edge. Now a different medium size circle and sew , and a small circle and sew. Then I cut each block into fourths. Aranged them on my design wall, starting with a mixed circle. Hope this makes sense.
