Well, that part was easy. What wasn't easy was what to do next! After a few different options, I decided to stick pretty literally to the sketch and go CAS.
Here's the sketch:
And here is my final card. I have another one that I may post later, but this is my favorite of the two I did.
I eyeballed where I was going to cut my circles and used my circle nesties. I then cut out smaller circles out of Very Vanilla and layered them behind the base. I then put some DSP behind the whole card front.
