It looks like she made three figure 8s and staggered them to make the petals. You can see how figure eights are made here (first three steps/photos only): http://tutusbowsandmore.com/pages/bo...winstructs.htm
The centers are small rolled rosettes made with grosgrain ribbon. A video showing how to make them can be found here: http://www.youtube.com/watch?v=NriXH3qMuqk
For the center you only want to go around two or three times, though.
Hope that helps.
