I know exactly what you are talking about but I can't remember where I saw the tut for this. I can try to explain:
1. Cut 6 6" ribbons
2. Center 1 of the 6" pieces on a needle and do a figure 8 with it.
3. Repeat for the next 2 6" pieces.
4. Sew a couple of stitches to secure.
6. Repeat for the next 3 6" ribbons.
7. Glue one set of 3 inside the next and finish off with a center.
*I typically put rhinestones or buttons in the middle.
