All layers of the daisy centers have slits cut around the outside edges. I used a quilling tool to roll each slit towards the center before gluing them together. The very center (green area) is green seed beads surrounded by yellow ones. I used a microwave kiln and fused them together. Of course, that is not necessary. Beads or many other things can be glued in the center. I just like to play around with different ideas. I liked how it turned out and will do it again.
