Swirl Cards

I tried my hand at making the fascinating (to me) swirl cards, and I am hooked.

The orange and coral card is on a light beige background and the circles are evenly centered on each other.

For a slightly different look, the blue circles (on a white background) are offset, changing the entire look. 

I already cut some pink circles to try this one again!  

I do not know if "swirl" is the correct word to use for this design, but that's what I am calling it.
