Living in orange country I have to say the linked flower is not a very good representation. The final picture on the pg is good but the way the flower is made isn't.
Study that pic. See how the petals are long? Not rounded like the 5 petal rose cutter will give you.
And the overall flower is small - about as big as a quarter.
The center is a deep cup; very small but deep w/stamen sticking out.
I suggest making the actual flower by starting w/a small teardrop of fondant - about the size of a large pea; cut it into 5 petals that you pull long and thin - just shape w/your fingers; dry them flat = not cupped. Make a small, deep cup w/jagged top edge and glue it in the center of the flower.
