Flood work is beautiful when done correctly. It’s kinda like coloring but for adults, you need to stay inside of your lines. Flood work is done with thinned royal icing. Patters are drawn or printed onto wax paper and than outlined with royal icing. First outline your pattern, once your icing starts to crust it is time to start coloring in your design. I would recommend not to pipe your color to your outlined border. Instead once your are finished with your first color I would get a toothpick and drag the color to the outline. This way you will be less likely to hit into your outline. Finished coloring in your design. Once your design is finshed let it dry. Dry times vary and may take up to 24 hours depending on how thick your icing was. Now that your design is dry peel it off of the wax paper and transfer it to your cake.
