I think it is a pinwheel on the bottom and then for the spikes I think she is doing them like you would a firecracker bow just didnt use as many ribbons. Then the top bow is just a two loop with tails.
Here is a great tut that I had bookmarked for the firecracker bows. Hope this helps. https://docs.google.com/fileview?id=...MGM0NDQ3&hl=en
