I have dabbled in cookie decorating and wanted to learn more techniques and especially about different thicknesses of royal icing. This class does a wonderful job explaining all the different floods, how to achieve them and how to use them. So helpful. The workbook is well designed and has so many illustrations that helped me each step of the way. I recommend Grace's classes to anyone who would love to make beautiful cookies. (My colors aren't a bright as I'd make them next time.)
