    Great idea. I believe that I would be successful following your easy directions. I can see the colors to be useful for a bridal shower using her wedding colors. Also, for baby showers in pink and blue. The colors are a nice pastel shade and that makes me think of relaxing topical themes. I can't wait to see how you use them. Thanks!

    Thank you. They do make nice pastel colors. You could add food color to darken them of course. I have also used Kool Aid to in my fondant. It has a much stronger flavor than Jell-O. So you just need a little of it.
