That cake always catches my eye...I think it is royal icing on fondant. Pipe the larger ones on parchment then apply to cake when dry. Pipe the smaller directly on cake.
I just found the book and they are called color flow bubbles. You need 100 each 3/4", 125 each 1/2", 225 each 5/16" and 950 each 1/8". You need to make them a day or two ahead of time to allow to dry. It is color flow icing which consists of powdered sugar, water and color flow mix. Hope this helps.
Vickymacd - Here it goes... The recipe for the Color Flow Icing is:
1/4 cup + 1 tsp water
1 pound (4 cups) confectioner's sugar sifted
2 Tablespoons Color Flow Mix (wilton makes it)
Using a wax paper-covered board or cookie sheet, just pipe the dots onto the wax paper. I would use a tip 1,2 or 3 to make the different sized dots. They form a bubble like shape and you need to let them dry up to 2 days in advance. The bigger the bubble, the longer the drying time. This technique and cake is on page 75 in the Wilton "Tiered Cakes" book. Hope this helps you out.
I have never worked with color flow....any tricks?
Color flow is pretty much like royal icing. It is thinner and usually used for filling in outlined designs. I learned this in the Wilton classes. It creates the bubbles by holding its shape. You probably could get more info on the Wilton website or googling it. Hope this helps you.
