Hi Tammie – it sounds more confusing when I try to write it than it actually is. Basically, while the flood icing (the red) is still wet, put dots of white (also thinned to flood icing consistency) on top. Then just drag a toothpick through the dot and it ends up looking like a heart! At least, it’s supposed to haha. Keep in mind that I always photograph the cookies that turned out the best… 🙂 Good luck! Let me know if you try it 🙂 I think that bakeat350.blogspot.com has an actual tutorial on it, but I can’t remember for sure.
