I used the circle scallop die (Spellbinders). I cut about 8 (didn't count) layers with two punches of the die. Then put them together with a brad in the center. With the layers matched up. I cut a slit between each scallop toward the center. Many of the slits are not straight as you have to be careful not to cut off the petals. Afterward I just squish TO the center from all directions. This will almost cover the brad so you can't see it. Just keep working- squishing it together until you are happy. If you try this with other than newspaper, let us know and how it came out.
I will have to give this a try Vicki - your flower looks so effective!
