I didn't get to the mica swirl challenge until today. So here it is. I'm pretty happy with the way it came out. I wasn't too focused on the swirl inside, moreso on the tops with the two micas. So here is the top of pure white, after pouring the swirl. Just fluffed it a bit:

Here is a quick cut pic! This was Fun! Really enjoyed all of the challenges!
