What you need:
Sewing pins in any color
I found it easiest to cut the scrapbook paper into strips wide enough to fit the flower punch, then cut about 10 flowers out of each strip.
Then put a pin through the middle of two flowers, pull the edges up to make it 3-D and arrange them so the petals are opposite. It's easiest to cover the whole Styrofoam ball if you start out by putting them close together.
