You can make a nice background for a cookie using just edible powder, either dry or wet.
For this cookie I dusted it first with #magic_colours powder and for the leaves I used the same powders in a wet version (diluted with liquor with hight % of alcohol).
The girl is entirely piped with coloured royal icing. Hope you like the idea. Thanks a lot, Marta! http://img.cakesdecor.com/f_auto/tuto_green_li0v5t.jpg!
