Custom circles alternate with posts

In the spun theme I have successfully created custom circles but can’t get them to alternate with my circles that link to posts. I have tried changing the post dates, but it doesn’t make a difference. So, right now I have a row of posts (which I can change the order of) and then a row of custom circles.

Does anyone know if there’s a way to get the post circles and custom circles to alternate with each other?

Thanks much.
