Look at these cute little billy balls, aka craspedia, nestled among roses and chrysanthemums. Using fillers like these in a flower arrangement creates contrast in both texture and size. It adds visual interest to the overall cake making it all the more beautiful. Small details like these are truly worth the effort and time. They are the backbone of a well designed cake. I have a whole section in my online buttercream flower class dedicated to fillers and foliage so check it out here!
