Hi Everyone! My bride wants to place this ceramic heart on her cake. The top tier will be a 6" square buttercream cake. I would use the SPS system on top but it doesn’t come any smaller than a 6" square and I don’t want it covering the whole top tier. Can anyone suggest how to secure this topper to the top tier so it won’t fall off as well as support it underneath so it won’t crush the cake? It is about 2.5 lbs. Thank you!!!!!
