Step 5: decorating
At this point, all you have left is the decorating. More royal icing can be colored and put in icing bags (or baggies). Icing gels give deeper color than regular food coloring and will likely be found in the same place you find your meringue powder. (see photo below)
The skulls can be decorated with a single color, or with as many vibrant tones as you desire. These skulls are meant to be more festive than frightening and thus, this is a project kids of all ages seem to enjoy. There are no rules in how you embellish, except for one:
Traditionally, the name of the deceased loved one you are remembering would be written across the forehead. You can also write it on a piece of colored foil and attach that with the icing.
Place your finished sugar skull in an ofrenda or anywhere else it will be visible and help you to remember your loved one.
