I had done this design last year when someone contacted me saying my picture came up in a Google search. This is a great design for those parents-to-be who are waiting for their arrival to see if they have a boy or a girl. On this design, I always let my white base dry for 2 days before adding the chocolate brown which is little thicker than my base consistency. I just add a little more sugar to absorb some moisture to prevent bleeding. I did the same with the pastels so they wouldn't absorb any brown while drying.
