I am quickly becoming a fan of color flow icing and you'll love it too.  It's so easy to decorate with and it hardens to perfection.  You end up with a nice smooth, shiny texture.
Pre-mix your icing and work quickly.  Color flow tends to crust over fairly fast.  Keep portions you are not working with covered with a damp cloth.  Here's the recipe.
Color Flow Icing
4 Cups of sifted powdered sugar
1 tbl of Color Flow powder by Wilton
1/4 cup of water plus 1/tsp
colors desired.
Bake your shaped cookies accordingly.
Let the color before adding icing.
Outline the shape desired and then fill in by simply piping the icing.
Use a tooth pick to give dimension.
Color flow is a fantastic medium to work with. 
Be creative and take your time.
Allow the icing to set over night.
We even tried a few acorns.
I can't wait to give another batch a try.  
P.S.  My little friend Ansley said my cookies were "good".  If she likes them, they must be delicious.

Husband and I are on a low carb diet and at dinner we had a classic BBQ feast to choose from; baked beans, slaw, pork, buns, the works.  How did I make this meal as "low carb" as possible?  I remade our own slaw and substituted a bun for a low carb wrap.
Low Carb Sweet and Spicy Slaw

• Angel Hair shredded cabbage (1 small package)
• Mayo (1/2 cup or to taste)
• 2 tbs Hot Vinegar ( hot peppers marinated in vinegar, pour the vinegar off)
• 2 pouches of Stevia (or other no calorie sweetener)

Mix  ingredients together.
Now pile pulled meat (in this case, pork) onto a low carb tortilla wrap.  FYI:  Whole Wheat does not equal low carb, check carbohydrate grams when buying.  Add a scant amount of BBQ sauce if regular or if you find a low carb brand you like.  Pile on slaw and wrap.  YUM!
