I've heard of people stamping designs onto fondant. Can this be done on RI? Is it just food coloring thinned with water or thinned with alcohol? And what is used to stamp? Can a regular stamp that's used for crafting be used?
Sorry, I misunderstood your question, on the link I gave you, I believe they stamp on fondant, but it is a neat website anyway.
I've never stamped color onto cookies iced with royal, but I have stamped piping gel onto them and then sprinkles the piping gel with colored sugars or dusts. The dress cookies in my photos have one that is a white dress with silver dust that was done that way.
I would assume that since that works, stamping color on would too....
Yes, it works. I find it hard to do though (probably because I really don't have the right tools). You are not supposed to use a wooden backed stamp because it is not food safe. The site that linedancer gave you is the place to go to find out about stamping. Good luck!
OK, I'm going to give it a trial run. I'll let you all know how it turns out. Thanks Linedancer for the llink. it was a neat site.
