AIm sorry if this has been answered already. I did do some reading but couldn't find the answer. I'm making a cake this week & really want to make the sugar tiles. I normally make regular buttercream but would like to make smbc or imbc this time. I don't really want to cover in fondant if I can avoid it. My concern is the sugar tiles 'melting' on the buttercream. I have made sugar jewels before & when I attached them to the buttercream they started dissolving. Is there a way to avoid this? Thank you in advance for any advice.

Maybe it's too late for an anwer,  but if you used Isomalt (I'm assuming you did) then it will be fine. I have made jewels and other decorations from isomalt and put them on a BC cake.
