Here is the entire collection

There are fabrics that you can use for whatever you like. I would start by "squaring off" the panel. It is currently about 24x42. So add some of the scalloped border fabric to complete the border, as mentioned above. Then add borders to your heart's content to get to what you want. A standard king mattress top is 76x80.
I would personally prefer subdued borders, so as to not take attention away from that beautiful panel--at least on the mattress top.
