I made a set of Mickey ears with royal icing and forgot to insert a stick. Now I have these great mickey ears that I want to stand up on a fondant covered cake and I don't know what to do. Is there anything I can use without making more royal icing to attach this to a dowel or sucker stick?

What about trying some candy melts or chocolate and melt them to use as glue.

I have the same problem...
What did you end up doing?
