In this video, we learn how to do gumpaste cake decorating lettering. First, you will roll the gumpaste, then add some crystal to the surface so it will stick. Next you will roll it out until it's thin. Cut a piece of it out, then put the rest on the side. Take the small piece and cut it into a small square. Use a letter Tappit to press onto it until it's completely cut out. Once finished, you will be able to use this on a cake! Cut out all of your letters from the remaining piece of gumpaste.
