Use wax paper to decorate cakes. Cut a piece of wax paper the same size as your cake, using the cake pan as a guide. Write directly on the paper instead of the cake and freeze it. Gently peel the frozen letters and words off the paper and place them on the cake.
Holy smokes. This may be the best crafting tip of the month. "print out the font you want and place wax paper over it. Trace letters with puffy paint, let dry, then use mod podge to secure letters to canvas, etc. Brilliant.".
