Well, two oval punches are better than one, right? Make oval rings by punching the small one first, then the large one. Turn the punch over to see where you're going.  I used an OnBoard chipboard flower as a guide to see where to place the petals, stuck them all together with Dimensionals, and secured it to the card.  The last step was sliding the small purple ovals under each petal... it's faster that way ;-)
