However, I do have pictures of a couple of cards with Fun Flock. I colored the images first and then apply the Fun Flock. I added the different colors one at a time to give the look of a gradual change in the color. My advice would be to get a few colors and white ... this will allow you to get different shades by mixing white into the color.
On this card, I add the fun flock on the head band and the collar and detail across the dress ... not sure if you could see this.
Here's a close up of the jacket ... I think you could see the texture more easily on this one.
