So I've been sitting on this pattern for a while because I just wasn't sure that I hadn't already posted it. But I trawled through my patterns and didn't see it, so it's probably one I was playing with at one time, and never got to the point where I did up the steps.
This makes a nice focal point (as a very perceptive Marguerite1997 pointed out), a single image or series of images that you use to add interest to something like Keeko or other background pattern. I like putting stripes in the 'petal' portion, but you could put just about anything in those spaces. But if your background is busy, keep Amaranth more simple to add contrast.
